Causes of dents in mould processing of automotive plastic parts

Plastic mould processing as a processing technology, after its production or completion, there will be some bad situation. How to solve this problem?
 
The causes of dents are as follows:
1) Insufficient cooling of the mould and insufficient cooling time will cause serious deformation.
 
2) Insufficient internal pressure of the mould will also occur.
 
3) The thickness of each part of the product is different. In this case, the overall treatment method is to reduce the barrel temperature and mould temperature, force cooling in the […]

Is there a company that offers quality custom plastic injection molding services in Shenzhen or Dongguan China?

Not all companies that plastic injection molding can meet the needs of their customers.
Sometimes, a company can not offer a complete service to a client because it has certain limitations, either of space, speed of manufacture and also of the customized creation of the requested design.
The companies involved in plastic injection molding know that sometimes customers request certain types of elements that are outside the standards they have in their most common designs, therefore, many of these have been […]

Detailed Explanation of Injection Molding Process for PP Plastics

“Plastic properties are the basis of injection molding technology”. Mastering the technological properties and characteristics of various plastics is a basic professional knowledge that every injection molding worker must know. The performance of plastics is the basis for setting “injection molding process conditions”. It is also the reason that must be considered when analyzing the quality problems and abnormal phenomena in the process of injection molding. One of the elements.
 
PP, commonly known as polypropylene, is also known as “100 […]

What Are The Characteristics of Injection Molds?

In the market, most of the molds we come into contact with are injection molds, which inject plastic materials into the molds to form the products needed for sale. In the mold industry, injection moulds are widely used. What are the characteristics of injection moulds? Injection mold is a kind of processing method used in batch production. It is mainly used in industrial field. The process of injection mold is to inject the melted material into the mold cavity […]

Attentions for Hot Runner Technology

Hot runner technology, with its unique technical advantages such as saving cost and shortening molding cycle, has become an important direction in the development of plastic injection molding technology. In Europe and America, most of the injection production relies on hot runner technology, but there are few enterprises in China using this advanced technology. But with the further development of China’s mold industry, this technology will be gradually promoted and widely applied. How to choose the appropriate hot runner […]

Benefits of using hot runner for plastic injection molding

Hot runner system for plastic injection molding saves plastic, shortens molding cycle, reduces production cost and improves efficiency. Hot runner mold is widely used in all developed countries and regions in the world. This is mainly because the hot runner mold has the following notable characteristics:
 
1, shorten the forming cycle and improve the production efficiency; because there is no restriction of the mainstream and secondary cooling time, the parts can be ejection in time when molding is solidified. Many thin-walled […]

TECHNICAL FEATURE OF PVC INJECTION MOLDING

PVC material is amorphism material, usually when injection molding the PVC material, it will also add stabilizer, lubricant, antiimpact agent and others. PVC material is with low flammability, high strength .PVC material Chemical and physical prosperity: PVC is the most extensive used plastic material.
Runner and injection gate: all the normal injection gate can use, if the plastic parts is very small, then it will be better to use valve gate or submarine gate, for the large plastic parts with […]

Avoiding Defects In Manufactured Plastic Parts

Quality Manufactured Plastic Components
When you employ a reputable plastics manufacturer, it shows. Unfortunately, when you hire a disreputable manufacturer, it shows more. When hiring a manufacturer, avoiding defects in manufactured plastic parts should be first and foremost on your mind. Here are some tips on how to avoid defects, for a near flawless production run.

These Three Factors Determine The Success Or Failure Of A Production Run:

The processing
The mold
The material

Making sure each of these elements is functional before the molding process […]

SOMETHING YOU NEED TO KNOW ABOUT INJECTION MOLDING

What is injection molding:
Plastic injection molding is a process that forces liquid plastic into a mold to make custom plastic name plates, plaques, signs and product branding elements. Once the plastic cools and solidifies, it releases from the mold to form a variety of plastic parts for any industry. Popular uses of injection-molded include: appliance name plates, name plates for industrial equipment, car emblems, vehicle branding and license plate holders, as well as product identification for recreational products.

Injection-molded plastic […]

RUNNER SYSTEM OF INJECTION MOLDS

When molten plastic material leaves the barrel through the nozzle, it is guided toward the mold cavity, its final destination. Its flow path is called runner system, such as the sprue, runners, gates. The runner is in a simple direct route or goes through a series if turns that the flow molten material twists, and restrictions as it approaches the mold cavity. The molten plastic material flows into this cavity, takes the configuration of this chamber in the shape […]
