Plastic Injection Tooling

Design of Wall thickness

Product structure is the key to the mould cost factors, to implement a function has a variety of different design, different design decision mold manufacturing method, determine the price of the mould is different also, some structure only requires us to pay attention to some design principles, maybe you can save a lot of cost, you can view our design guidelines to learn.
 
If we ignore the wall thickness of the product, the appearance problems caused by the uneven wall […]

How to finish the mold processing order on time

How to ensure that the mold processing orders can be completed successfully?

Size

Each customer if wants to choose, to ensure their own mould processing orders can be smoothly in a short period of time, it is best to also will be able to determine the size of each enterprise, that is to say as far as possible the choice of more large-scale enterprises, because of massive basically in this aspect of an enterprise is not likely to be some delay, […]

Basic parts of plastic injection mold

No matter what kind of mold is inseparable from the components, plastic injection mold is the same. Here Jasonmould shares you the basic parts of the plastic injection mold.
 

Forming parts, including the die, punch, a variety of forming core, are forming products inside, outside the surface or upper, lower end, side hole, side concave and thread parts.

 

Support fixed parts, including mold seat plate, fixed plate, support plate, pad, etc., to fix the mold or support pressure.

 

Guide parts, including guide […]

Heat treatment and production process of precision injection molding

In the process of heat treatment, the deformation of precision injection mold often occurs. In order to prevent this kind of bad phenomenon, as long as we grasp the deformation law and analyze the causes, different methods can be used to prevent the deformation of mold, which can be reduced and controlled. In general, the following methods can be adopted to prevent the deformation of precision injection mold during heat treatment.
(1) Reasonable material selection: for precision injection mold, micro […]

How to reduce the cost of plastic mold

Reduce the cost of plastic mold processing, can effectively improve the economic benefits of plastic mold factory production, conducive to the plastic mold factory and product market competitiveness. If the plastic mold factory can reduce a variety of unnecessary waste, so as to achieve reasonable storage, use materials, reduce costs, improve the purpose of efficiency, so as to ensure the reasonable needs of production, but also to reduce the use of capital and waste. So, what is the plastic […]

The advantages of spray painting on the surface of plastic parts

The surface of the plastic part can be sprayed to ensure the brightness of the product. Because plastic is so hard to embody, plastic parts look darker, and even darker if they are covered in leather. Therefore, in the pursuit of a beautiful surface, Some customers requires to spray a layer of  painting on the surface of plastic parts. This will ensure the brightness of the product.
Spraying the surface of plastic parts can reduce the scrap rate of parts. […]

Factors affecting the number of cavities in Plastic Injection Molds

The cavities in Plastic injection mold is not the more the better, also not all molds can be done with 4 cavities or 8 cavities. So what are the factors affecting the numbers? Let’s have a look below:

Relationship between the product size and equipment.

When the part belongs to large or medium size, generally speaking, single cavity is used. On the one hand, it is necessary to consider the fluidity of plastic material filling mold when injection molding, so as […]

Forming characteristics of ABS in plastic injection molding

Today, we would like to introduce the forming characteristics of ABS in plastic injection molding.
 
1.ABS is easy to absorb water, and should be dried before forming. Plastic parts with high surface gloss requirements should be preheated and dried for a long time
 

Medium liquidity, about 0.04mm overflow edge.

 

The wall thickness and melting temperature have little effect on shrinkage, and the size of plastic parts has high precision.

 
4.ABS has low specific heat capacity, high plasticization efficiency and fast solidification, so the […]

How to prevent stripe defects in precision injection molding?

As we all know, the stripe defect in mold is a very serious matter, it will directly affect the accuracy of injection molding, and will also lead to product scrap, so we must pay attention to. So, how can we avoid this defect?
Proper design, careful processing, reasonable mold repair and timely nitriding are the key measures to prevent the occurrence of stripe defects in precision injection molding.
It should be processed in strict accordance with the requirements of the drawing, […]

Discoloration of common problems in plastic injection molding

Discoloration refers to the inconsistency between the surface color of the formed parts and the required color. Discoloration may be caused by a variety of reasons, including injection molding machine, plastic mold, injection process and raw materials.
(1) Injection molding machine
① The equipment is not clean and needs cleaning. Dust or powder deposited in the barrel contaminates and discolors the material;
② Temperature control fault caused by temperature controller or heating system fault;
③ There are obstacles in the barrel, which lead […]
