Trusted China Pet Bottle Manufacturer – Jilian Plastic Mould

The bottle used for the bottle we are using is mainly made of Pet Preform. If such a polymer material is inadvertently produced, various problems will occur. The more common one is When the bottom of the bottle is whitish, today we will come together to see why he has such a situation.

The main reason for this is that it is produced in the production of transparent or nearly transparent bottles, because only such a bottle has a white blush at the bottom to be able to visually appear, affecting such a large, in fact, he appears The situation is mainly in the case that the temperature of the hot runner is insufficient, which means that the temperature should not be so high when the purification should be performed, resulting in insufficient purification, because the plastic at the bottom is relatively thick, so it is needed. When the time is compared, the temperature maintenance is also required to be relatively high.

The solution is also very simple. Firstly, the temperature should be kept constant while maintaining the temperature, and then the excessive heat loss should be prevented, and the speed of the process should be increased, so that the process can be ended in the shortest possible time. Effective use of heat to do more big things, so that the quality of pet preform plastic produced will be better, and the bottom of the bottle will not appear whitish.

How Long Is The Development Of China Pet Bottle Manufacturers?

When the Pet Preform manufacturer develops to a certain stage, we have to look back. Examine yourself. I always think that when the PET bottle manufacturer is developing, it is also the time when the problem is accumulating. Because development and problems are always the same, this time I need to examine myself to reflect on the problems that may exist. Because this time does not reflect, it may accumulate for a while, and the problem will become impossible to solve. In the rapid development stage, PET bottle manufacturers will be accompanied by those problems. First, financial resources. Rapid development means a large amount of income, but on the other hand, it means more investment and greater demand for funds. . What happened at this time was the break of the capital chain. Like the giant group of the year, the current Prince’s milk, the main reason for their failure is the break of the capital chain. Therefore, this is a question that needs to be examined by oneself. Is your own fund sufficient for your own development? Have you considered whether there is a shortage of funds in the event of a shortage of funds, whether there is a new financing channel or an organizational problem. In the final analysis, the organizational problem is the human resource problem. With the rapid growth of PET bottle manufacturers, the demand for talents will become even bigger. Maybe we can solve other problems. Only the problem of talents is the problem of PET bottle manufacturers. root cause. The lack of talent reserves, the cultivation of talents can not keep up, these are the hidden dangers behind the rapid development of PET bottle manufacturers. Another is that with the development of PET bottle manufacturers, employees must increase, so is the organization structure of employees reasonable? Does the employee have behaviors that are superfluous? Whether employees are as passionate as when they first started business is a strategic issue. When the PET bottle manufacturer is small, we rarely consider where the PET bottle manufacturer goes, but when it reaches a certain scale, no matter where the PET bottle manufacturer goes, it is not far from the door. Consider what our long-term business is? What is our mission? What is our main business? Can we have a new development business? Are we going to concentrate or diversify? These need to be considered.
Re-examine your marketing situation. CEOs must care about sales. Because with the rapid growth of PET bottle manufacturers, the market will be filled from blanks, which is bound to be a process from extensive to fine planning. Considering the intensive cultivation of the market, there is a marginal effect in economics, because With the growth, easy development has been developed, then for the development is not easy, we have to pay more, we must intensively work in order to truly develop. Re-examine your market input and returns. To re-examine its own market strategy, it is to bloom in full, or to focus on key breakthroughs in resources.
Re-examine your management issues. Along with the rapid development and expansion of PET bottle manufacturers, it will inevitably lead to management incompatibility, and it will encounter situations where management is uncontrollable. At this time, with the development of PET bottle manufacturers, change their management methods. Learn to decentralize and learn to mobilize the enthusiasm of subordinates. Gradually integrate various departments, clearly define the division of labor, and learn to use the system to manage. It is necessary to gradually establish the PET bottle manufacturer’s own PET bottle manufacturer culture. To lay the foundation for the long-term rapid development of PET bottle manufacturers.
Importantly, it is necessary to clarify that with the rapid development of PET bottle manufacturers, the factors that determine the development of PET bottle manufacturers will become more, and the problem may be that PET bottle manufacturers face considerable difficulties for rapid development. It is important for the PET bottle manufacturers to reach a certain stage to develop harmoniously. It is necessary to grasp the relationship between the various factors affecting the development of PET bottle manufacturers. It is necessary to pay attention to the coordinated development between the various elements, so that the PET bottle manufacturers can coordinate development. Stable development and long-term development. This is our common goal.

Injection Molding Conditions For Pet Preform

In addition to the extrusion molding process, Pet Preform are mostly injection molded to produce preforms.
In the whole preform processing equipment, in addition to the injection molding machine, it also includes: hot runner mold, ester particle dehumidifying dryer, mold cooling ice water machine, preform removal robot arm, preform conveyor belt and injection environment control air conditioner dehumidifier, etc. And each machine is to cooperate with the action of the injection machine, so the injection molding machine plays the most important role in the preform molding process.
In general, the main process control parameters of the injection machine are: (1) screw speed; (2) injection pressure; (3) injection speed; (4) tube temperature; (5) nozzle temperature; (6) pressure holding; 7) Pull loose; (8) Switching mode speed; (9) Cooling time; (10) Cycle time. Each parameter is related to the quality of the injected product. Therefore, the control of the parameters is very important. In order to achieve good process parameters, the performance of the injection machine must be designed in accordance with the process requirements.
Screw design

The general screw is used for the injection of PET, which is of poor quality and is prone to problems. Therefore, the PET injection machine must have its own dedicated screw. Because PET is a heat sensitive material, it is easy to break the molecular chain at high temperature, reduce the molecular weight, produce acetaldehyde, and reduce the quality of the preform. In the material tube, the screw is compressed by the screw to melt heat. If the shear heat generated by the screw compression is too large, PET thermal cracking may occur. Therefore, the PET injection screw must have a low shear design and can melt the crystallized PET ester particles. Too high compression ratio or too short compression length will cause large shear; while too low compression ratio screw will produce insufficient shear heat, which may not completely melt the ester particles, so that the preform crystals are white atomized and cannot be The air inside the tube is completely removed, which makes it easy for the preform to generate air bubbles. The screw design of the PET injection machine is important for the injection molding process of Pet Preforms.

The Impact Of Temperature On The Application Of Pet Preform

When parts molded with Pet Preform have melting temperatures of 400°F and 480°F, they have better impact resistance, have shorter mold cycle times, and consume less during plastic molding. energy.

*Examples provided by plastic technology
Mold temperature

In plastic molding, improper mold temperatures can cause defects such as mold warpage, dent marks, and jetting.
Mold temperature effects…

Depending on the type of resin used, mold temperature can affect performance, for example:

Molded stress
Creep strength
Dynamic strength
Wear resistance
Molecular weight
Dimensional stability

Mold temperature problem

Mold temperature is inconsistent
Mold temperature is inconsistent with part cavity proximity

Example of the effect of mold temperature on parts

When parts molded in polycarbonate have a higher molding temperature, they will have a lower level of molding stress, which results in increased resistance to stress cracking, impact and fatigue.
Plastic molding melt temperature and mold temperature considerations

It is important to understand how the melt temperature and mold temperature work together to produce the final part characteristics.

In most cases, a lower melt temperature plus a higher mold temperature will result in the best performance.

However, many push-button plastic injection molding machines do not have the technical expertise to implement and monitor the two key aspects of plastic molding. Instead, they believe that high melt temperatures are the only solution to reduce the viscosity of the resin.
Higher melt temperatures can cause…

Unfortunately, higher melt temperatures can result in:

Resin degradation
Longer cooling cycle
Increased energy consumption

These plastic molds are now forced to lower the mold temperature to recover the lost productivity due to the long cooling cycle caused by higher melt temperatures. This ratio of high melt temperature to low mold temperature often results in impaired component performance and component instability.

How To Save Cost In China Pet Bottle Making

For the China Pet Bottle mold injection system, the most common way is the cold runner, hot runner opening door, hot runner valve, the price from low to high, why customers still choose expensive valves? What are the advantages of the valve?

About cycle time

Cold runner molds, cold runners are always thick because the runner size is always thick, and cooling takes time, so the cycle time is always not short. Especially for lighter weight products, the cold runner has no advantage.

Hot runner open gate mold, even if it does not need to wait for the gate to cool, but it has a gate size limit, usually the hot runner open gate size should be greater than 2.5 mm, otherwise it will have a tail, not beautiful fracture.

The hot runner valve gate mold does not need to wait for the gate to cool. At the same time, the gate size is smaller. It can make the gate 4 mm or even 6 mm because the valve pin can help cut beautiful materials. The larger the gate size, the easier the material flows and the faster the filling speed. This is also the reason why some refractory materials use valves better, such as PC and PMMA materials.

Therefore, by comparison, the hot runner valve can achieve the shortest cycle time in these injection modes.

About cost

Even if you start spending more money on the mold, is it really the most expensive way? Have you calculated the actual cost of the entire production?

A. Compared with the cold runner, there is no need to manually cut the gate, which saves a labor cost, the runner has no waste, and the material cost is saved.

Production costs, as mentioned above, the valve can achieve the shortest cycle time, using the same machine every hour, it produces more pcs, which means that the cost of each product is lower with the valve mold.

Of course, making comparisons requires precise calculations. For a small number of products, the valve may not be competitive, and the more the quantity produced, the more savings will be made.

China Pet Bottle Welcome Consultation

It is important to understand the Pet Preform blow molding process so that you can successfully design and manufacture the parts or products you want. Ideally, you will end up with a high quality product that is efficiently created with as little waste as possible.

What is blow molding?

This process is used to make plastic hollow parts (such as bottles and containers) where air pressure fills the mold cavity with soft plastic.

Blow molding is divided into two steps:

First, a starting tube (called a parison) of molten plastic is produced.
Next, inflate the tube to the desired final shape, cool it, and release it from the mold.

Blow molding materials and products

Blow molding is limited to thermoplastics:

Polyethylene – the most commonly used polymer. In particular, high density and high molecular weight polyethylene (HDPE and HMWPE) provide the hardness required for the finished product, making the use of these materials more economical.
Polypropylene (polypropylene)
Polyvinyl chloride
Polyethylene terephthalate

Blow molding project design process

A well-designed design is critical to creating a finished product that meets your exact needs while saving manufacturing costs. Here is a brief overview of the design steps to bring your product to life:

Create a model of the part. The store team created a 3D drawing with a CAD program, which allowed you to see your product accurately before making a physical mold.

China Pet Bottle Usage Is Growing Rapidly

Development status and trend of global non-fibrous PET

Non-fibrous PET was first introduced by Kodak as a substrate for photographic film. Since the mid-1980s, Coca-Cola introduced this variety into the beverage packaging field. Since then, non-fiber PET has developed rapidly and has been developed into bottles. , film, sheet, engineering plastics, packing belt (plastic steel belt) and other fields, only PET pellets for food grade bottles have mineral water, carbonated beverages, hot canned beverages, white wine bottles and beer bottles, etc. Classification. The global PET production capacity for packaging in 2005 reached 14.5 million tons, and its distribution is as follows:

China’s packaging and non-fibrous PET started late, but it has developed rapidly. In 2005, China’s Pet Preform production capacity reached 3.1 million tons, and the output reached 1.7 million tons, of which 1.2 million tons were sold domestically and 500,000 tons were exported. According to the current consumption of PET in bottles in Europe and the United States (17KG/person in the US, 20KG/person in Europe) and the proportion of total PET production capacity, there is still much room for development of PET production for packaging in China (currently 1.3KG/person), it is expected that its growth rate should be 15%/year, which means that the production capacity will be close to 6.5-7 million tons/year by the end of the 11th Five-Year Plan.

Conclusion: Due to the rapid growth in the use of disposable China Pet Bottle, new pressures are placed on environmental protection in China and the world. We often say a word “waste is put together as garbage, and waste is placed separately as a resource.” If we can do a good job in the recycling and utilization of waste PET, it will not only reduce environmental pollution, but also provide a new raw material route for human beings.
