Injection molding offers a wide range of options for the manufacture of Pet Preform Mould because the nature of the process means that it is suitable for the design and type of many parts and products. In addition to the standard injection molding process, more versatility and efficiency can be achieved by two-component injection molding. As the name implies, two-component injection involves the use of more than one material in the forming of a part. This is different from the more typical one-component injection molding process in which only one base resin is injected into the mold.
Two-component injection molding can be achieved in several ways, each producing different results and effects. Below, we will review one by one:
Mixed materials: In two-component injection molding, which may be considered the simplest form, the two materials can be fed into the injection molding machine at the same time and mixed while heating. This method can be used for aesthetic purposes. For example, the dye is mixed with a resin to achieve a different color or an attractive appearance of the finished product. It can also be used to obtain physical properties different from just one resin. For example, a harder resin is blended to reinforce the parts that are primarily made of softer plastic.
Co-injection molding: In co-injection molding, two complete materials are injected into the cavity, one after the other, causing the materials to harden around each other while becoming fully bonded. This process is useful for creating a soft rubber shell around the hard plastic core.
Double injection molding: In this process, different materials are fed into the mold cavity at different points through different gates. They begin to harden before the meeting point in the cavity, creating a stratification effect. In co-injection molding, these materials are not intended to be physically mixed together. The meeting point of the two materials, as well as the appearance and function of the finished product, can be adjusted by fine-tuning the injection speed of each material.
Multi-injection molding: In multi-injection molding, a “layering” effect is achieved by sequentially injecting a portion of the material into the mold cavity. These materials do not mix with each other and do not harden each other. Instead, they are “stacked” into finished products. Multi-injection molding is also called sequential molding.
Overmolding: In overmolding, multi-part parts are constructed by an “additional” type of process in which one part is constructed and allowed to cool and harden completely, then another part of the part is molded around it ( Or “above” when used as a pedestal or core. Overmolding allows for a wide range of flexibility in materials and structures, as the core does not even have to be injection molded (or plastic). For example, a rubber handle can be overmolded around the metal piece.
As a professional China Pet Bottle manufacturer, Jilian Plastic Mould has rich experience in injection molding, and is constantly upgrading its production technology to develop more efficient and diverse injection molding technology.
Let us delve into the three reasons for the design and manufacture of domestic Pet Bottle Mould parts.
1) Cost can be offset
The survey shows that most Chinese prefer to buy Chinese-made products, even if they have to pay a premium for it.
According to a survey by the Boston Consulting Group, nearly two-thirds of Chinese consumers say they are willing to pay up to 10% more for these products.
2) International visibility
According to DIRC research, even Chinese consumers prefer Chinese-made products and are willing to pay more. Given China’s dominant position in manufacturing, this may be surprising.
3) Plastics create jobs
The plastics industry employs nearly 1 million people in China. If you also include plastic suppliers, this number will jump to nearly 1.4 million jobs.
Murray Plastics believes in China’s manufacturing industry. As a proud supporter of the Georgia Manufacturing Alliance, we strive to source our materials and sell our products in Georgia.
We hope that Gianlian Mould can manufacture your 5-gallon Pet Preform products or parts in China and maintain competitive costs and lead times on a global scale.
In recent years, China’s Pet Bottle Mould industry has developed rapidly, and the market competition has become increasingly fierce. Especially after China’s accession to the WTO, many foreign mold makers have entered the Chinese market.
Although the growth of export molds and mold parts has been greater than imports in recent years, the absolute value added of exports is still less than imports, which makes the trade deficit of the mold industry increase year by year. Finally, until 2006, the situation improved and the deficit fell slightly. There are two main factors contributing to the increase in the trade deficit of the mold: First, with the rapid development of the national economy, especially the strong mold demand generated by the rapid development of the automobile industry, domestic mold resources cannot meet the needs of the domestic market, and even some high-end Molds are also not available in China, so imports are increasing; second, they are related to China’s current tariff policy and project approval system. At present, like other mechanical and electrical products, the export tax rebate rate is only 13%, not more than 17%.
According to the “China Injection Mold Industry Development Prospects Report”, it is very important to stand out in the fierce competition and vigorously develop the international market. The best way is to reduce the cost and time of mold manufacturing without sacrificing quality.
It is very important to develop mold standard parts and make them as professional and mass production, which can save time in mold design and manufacturing, reduce mold manufacturing costs, and improve mold quality.
In Jilian molds, we not only standardize mold parts and inserts, but also standardize mold bases called MUD (mother mold) systems. Jilian mold can help you save a lot of time and cost, from small batch production to high volume production. No matter what your mold needs, Jilian mold can satisfy you. Our 5-gallon Pet Preform have also been recognized by many customers. Our professional team can provide you with special design solutions!
As an industry leader in gas-assisted Pet Bottle Mould injection molding, Jilian Plastics has a wide range of forming capabilities to meet the diverse needs of our customers.
Gas-assisted injection molding can increase dimensional stability and reduce costs compared to conventional manufacturing techniques such as structural foam molding and thermoforming. By injecting a controlled gas flow into the mold, the thick wall is formed by the hollow portion, saving material, reducing cycle time, and reducing the pressure required to mold large plastic parts with complex designs and attractive surface finish. All of these benefits are achieved without compromising the structural integrity of the molded part.
We offer internal and external gas-assisted injection molding, which allows us to create countless complex part geometries that were previously impossible with injection molding. Brackets and brackets do not require multiple parts that must be assembled in the future, but are easily integrated into a mold without the need for complex cores. Multiple injection molding machines are capable of producing parts from 10″ to 80″ long, 10″ to 70″ wide, and 5-gallon Pet Preform. Our customer base includes OEM manufacturers, laboratory and diagnostic equipment designers, medical device manufacturers and large office equipment companies in retail kiosks that provide automated services. In addition to gas-assisted molding, conventional injection molding and structural foam molding are also possible. Value-added services, including painting, insertion, printing, assembly and packaging, provide customers with a single source of turnkey injection molded parts.
When you ask for a quote for a Pet Bottle Mould or product through rapid prototyping and quick tools, you feel like you’re being shot in the dark, and it seems difficult to predict price and time. But in fact, there are several aspects we can estimate the price and time you will receive.
Quick tool, rapid prototyping
The material of the part (plastic or metal), the size of the part, the manufacturing process and the finish used, the tool requirements and the quantity requirements, all of which are related to the cost of manufacturing the part. Here, we want to share some basic guidelines to give you a better understanding of the factors that affect manufacturing costs.
1. Material costs
The materials you choose will affect the cost of your project. Material costs around the world are slowly adjusting, and by understanding the local material costs, you can get an overview of raw material costs. Cheaper materials may mean that your products are less durable or of lower quality, and more expensive materials increase manufacturing costs, but you can get higher quality products for longer durations.
2. Quality requirements
When your parts start to produce, you pay for the quality. Reliable manufacturers place great emphasis on quality control, which helps ensure that your product meets your specifications and you will encounter fewer problems and avoid moving around. In the long run, you can save money by investing in quality.
3. The materials required for different capacity molds are different, so the price is naturally different. The material cost required for a 5-gallon Pet Preform is naturally different from the cost of other specifications, and it is naturally higher in terms of cost and price. I believe everyone can understand.
Plastic molding is an extremely versatile process and application. Therefore, innovations, trends and opportunities in the industry where plastic molding is widely used often represent the same possibilities for the Pet Bottle Mould itself. As designs, materials, regulations, and consumer/buyer needs and tastes continue to evolve, plastic molding has no choice but to follow suit.
Plastic molding machine
Fortunately, in order to keep up with these trends and innovations, the core process of plastic molding does not need to change. With the basic process of plastic molding, manufacturers and entrepreneurs already have a core set of tools that need to iterate, plan, and think outside the box to take advantage of the possibilities of plastic molding.
Smaller and better
As minimally invasive surgery and implantation become more and more a norm while continuing to provide patients with higher quality care, smaller but more effective medical components are a mainstream trend in the medical field. Injection molding has a set of “burn-burn” best practices that help medical manufacturers and innovators design devices that meet these needs while providing unparalleled accuracy, strength and durability.
Material innovation medical plastic molding
In all other industries discussed here, material formulations are still innovating to make plastic molding more efficient, easier to obtain, and easier to mold. Especially in the medical industry, materials remain a key issue because the base material must be suitable for safe use in the body (biocompatibility) and can withstand the often harsh internal environment. Safety remains the most important issue in the medical industry, so any newly developed material formulation must be extensively tested and approved before use. The complexity of forming multiple materials is becoming an increasingly popular process, meaning that material interaction, safety and accountability are more important than ever.
Under the great development of the plastics industry, Jilian Plastics continues to innovate and constantly surpass itself, so that our company can have constant possibilities. 5-gallon Pet Preform and machines are the result of our constant innovation.
The development of our plastic injection molds depends on the development of the plastics industry. The development of plastic products is accompanied by the inevitable requirements for the development of Pet Bottle Mould. In recent years, the plastic mold processing industry is also developing rapidly, and the plastic mold industry is also growing rapidly.
Through domestic and international exchanges and cooperation, the main problems will be gradually solved better under the joint efforts of the whole industry and the joint support of all parties. There are still several problems in China’s plastic mold industry to catch up with the advanced level of foreign countries.
1. The development is uneven and the overall product level is low. Although some plastic mold company’s products have reached a very high level, close to international standards, but overall, precision mold cavity surface roughness, production cycle, life expectancy and other indicators compared with foreign advanced level for more than 10 years gap.
2. Technology and equipment are backward and organizational coordination is poor. Although some companies have more advanced technology and equipment levels through technological innovation. But most companies are still relatively backward technology and equipment. What’s more important is that our company is organized and coordinated. It is difficult to integrate or mobilize social resources well, so it is difficult to undertake large-scale projects.
3. Most plastic mold companies have weak development capabilities. On the one hand, the proportion of technicians is low and the level of technicians is not high enough. On the other hand, R&D investment is less, and more importantly, the idea behind development is ignored.
4. Management problems are not just technical backwardness. Technical backwardness is often easy to see, but it is difficult to recognize management issues. The gap between plastic mold companies at home and abroad is very obvious, especially in terms of management.
5. The development of production cannot keep up with market demand. The contradiction between supply and demand is difficult to solve. The supply situation will continue for some time, especially for some high-end or innovative products, such as 5-gallon Pet Preform.
You may not think how Pet Bottle Mould affect our daily lives. For you, it may look like a piece of ordinary plastic, but this plastic hardware is more than it looks.
There are also many types of plastic molds that differ in the materials and uses used. Some are made of bronze and brass (a combination of zinc and copper), while others are made of nylon or other types of durable plastic.
With this knowledge in mind, you may want to know how to find the best plastic bottle mold.
Don’t worry! We are here to help. To get you started, here are some things you should consider.
What kind of plastic bottle mold are you looking for?
This is the first question you should ask yourself. Then ask yourself these follow-up questions:
Does your outdoor gear need it?
If you have already asked these questions, it’s time to move on.
Who is the manufacturer?
There are many manufacturers outside. You may have a hard time finding it, so we made a list to make your search easier.
Are their factories in the same state or country as you?
Are their manufacturing costs within your budget?
Are they willing to work on your project ideas?
Do they use durable raw materials?
Are they delivered on time?
Do they have satisfied customers?
Do they work with plastic mold suppliers?
If the answer to most questions is yes, then you have a good candidate to make your plastic bottle mold.
What is the record of the plastic bottle mold manufacturer?
Knowing a company’s proven track record is critical. Producing top-of-the-line custom 5-gallon Pet Preform molds is not an easy task. This is another checklist we make to determine if a company is right for you.
Do they take their work very seriously?
Do their products go through a rigorous process from start to finish?
Do they carefully inspect each product at each stage to ensure it meets all quality assurance and quality control procedures?
Do they have several years of experience in mold making?
With this knowledge in mind, are you still willing to work with companies that produce low quality products, or are you ready to invest in a reliable company? this is your choice!
What kind of shape do you want? The Pet Bottle Mould can accurately give a specific shape in the molten plastic state. Today, plastics are widely used for their high durability, not traditional glass, wood and other materials. Plastics are molded into the desired shape using a variety of techniques, and plastic injection molding is one of the most valuable and cost-effective molding techniques available today.
Color injection molded plastic parts
One advantage of plastic parts is that they can be made in any color you want, and unlike metal parts, it is easy to make plastic parts in different colors. Most consumer products need to be rich in color, and your mobile phone, car, and color may be one of the main reasons why your customers pay for your products. Therefore, how to define colors and custom products is one of the important factors to achieve large-scale sales.

Please note that all molds/parts are custom made for specific customers, and anyone interested in selling these products should contact our customers directly.
US and China in injection molding
Low cost production
China’s labor costs are still much lower than in the United States. In the past 10 years, the Chinese labor force has grown every year, about $500-$1,000/month, but don’t forget the productivity of personal labor growth. Low-cost production remains one of the main reasons why China maintains its strength in the injection molding industry.
Although there are still “bad” labels in the impression of many people in China, you can’t just see such an aspect. China still has a lot of good quality products, and the 5-gallon Pet Preform of Jilian mold. Billets, molds and equipment have enjoyed a good reputation in the global market. All you have to do is get ready to find a reliable Chinese mold maker, because low quality products are there, even in the US!
First, product acceptance
In China, after injection Pet Bottle Mould must go through several test modes, most small and medium-sized molds will have 1-3 trials, medium-sized injection molds need 3 to 5 times, and molds with particularly complicated molds will be more likely to be tested. .
How many times the molds and equipment and the operation process are closely related to the quality-related injection mold design and production quality. At the same time, it reflects the technical level of the mold factory to a certain extent. The sample that best reflects the injection mold level is the last sample of the test specimen. Samples are usually sent to the ordering party to check the results as an important basis for mold inspection time. The correct size of the basic sample may reflect the manufacture of precision molds. Therefore, in the acceptance process, the product to be accepted first.
After completing the processing within 16 hours after acceptance, at least in the molded plastic part or the required part. The acceptance standard ambient temperature is 23±2°C, the relative humidity is 50±6 %, the dew point temperature is 21°C, the atmospheric pressure is 890～1060 HPA, and the wind speed is ≤1m / s. If the actual environment is not standard, it can be performed under both conditions, or the length expansion correction factor corresponding to the measured value.
1. Test the basic dimensions of the product
When obtaining a sample, first observe whether the overall shape is correct and whether the basic shape conforms to the product design. Then test the basic dimensions of the product.
2. Product with test size
An item of the same size as the size refers to the interaction between the product product and related components, or the interaction between the product product and related components, including local relative position to the dimensions and overall dimensions.
3. Test assembly inspection
When the basic size, size, and inspection size of a 5-gallon Pet Preform are considered to meet the design requirements, you can try assembly inspection. This is a very important means of inspecting the product. The dimensions of the inspection space surface can be tested for inspection. .
4. Product appearance quality inspection
When pre-satisfying the requirements, it is necessary to conduct a comprehensive inspection of the apparent quality parts, then the apparent quality means that there is no common defect condition and the apparent quality meets the requirements.
5. Balance and static balance test
Dynamic and static balance test is carried out on high-speed components; the strength of parts is required to be high, and impact test, strength and high temperature test are required.
