Plastic Injection Tooling

In the process of injection molding, we should carefully look at the following four points

In fact, injection mold is a procedure for producing plastic materials, but some attention should be paid to in the injection molding process, because carelessness will deform the materials and make them unusable. And the mold has the nickname of “mother of industry”. It can be seen how important the mold is. Here are four points to pay attention to in injection molding.
1. Good wear resistance. The gloss and accuracy of the surface of injection molded parts are directly […]

Is the injection mold simple? That’s just what you see on the surface

We all think that the structure of the injection mold is very simple, because we only see the surface, but we don’t know that a design is designed to design a mold, but it takes several days to draw a 3D drawing and then convert it into a 2D drawing. During this period, the designer has to go through a lot of tests and judgments when designing each ejector rod, otherwise it will cause the dislocation of the ejector […]

What is the to reduce the use time of precision mold processing?

What are the factors affecting the service life of precision mold processing? Here, Dj molding has sorted out some contents for you. Come and have a look.
1、 The main factor is corrosion failure. When the mold hardness is high, the corrosion resistance is good. If the die hardness is poor, the corrosion resistance is poor.
2、 Thermal fatigue crack damage failure, injection molding and mold are formed repeatedly under the action of cold and heat to form surface and internal […]

How to screen injection mold manufacturers?

With the continuous progress and development of science and technology, the competitiveness of the mold industry is also increasing. For example, in the industry with relatively low threshold of plastic shell injection mold processing, there are many manufacturers with different sizes and small ranges, which makes it difficult for many customers with real demand to find quality manufacturers.
Then Dj Molding will share with you some tips on how to select high-quality manufacturers in many injection mold processing. First of […]

Mold processing needs to be carried out according to the specified process to ensure its accuracy and quality

Mold processing needs to be carried out according to the specified process to ensure its accuracy and quality. Mold processing is a complex process, so we must be careful in processing. What is the processing flow of the mold? Let’s talk about it in detail.
1. Mold blank preparation
Most of the raw materials are metals. From the perspective of forging, the raw materials used are usually bars, plates and pipes. Operators should choose according to the shape and set size […]

Solution to the problem that injection mold cannot exhaust

When the injection mold is opened, the mold often can not exhaust. How to solve this situation?
From the design process of injection mold, the exhaust of injection mold is through the gap between injection mold parts. Most injection molds with small volume can exhaust naturally by using the clearance between the parting surface of the mold, the fit clearance between the push rod and the push rod hole and the fit clearance of the movable core hole.
For example, if […]

Dj molding shares with you the performance of the mold

With the development of society, molds are widely used in many fields. Mold designers must have rich experience in design and injection molding, and must consider the relationship between these influencing factors and injection molding conditions and their apparent factors. Because most of the working conditions of molds are poor, molds need to have a lot of performance. Now let’s follow Dj moldingto learn about it.
Folding high temperature performance
When the working temperature of the die is relatively high, it […]

Why do you use auxiliary equipment in mold processing

Injection mold processing needs various process requirements. In addition to the specified host, it also needs a large number of auxiliary equipment to help complete various processing procedures. The automation, rationalization and perfection of auxiliary equipment determine the viability of products and enterprises to a certain extent, so auxiliary equipment plays an important role in production.
According to the function, it can be divided into three categories: feeding system equipment, corner waste recycling and temperature control system device. It also […]

What abnormal problems will injection mold encounter

As we all know, all kinds of tools and products used in our daily production and life, from transportation to buttons and the shell of various household appliances, are closely related to the customization of injection mold. The shape of the mold determines the shape of the product, and the processing quality and accuracy of the mold also determine the quality of these products. But do you know what abnormal problems often occur in PC injection mold products? So […]

What’s wrong with the poor effect of injection molded products

In the production of some parts or objects with the help of injection molding molds, some products will have unqualified appearance and quality, which is a kind of problem that often occurs in the production process of injection molding. What factors may lead to the poor effect of injection molding products? Now let’s learn about the incentives.
Defects in the shape or quality of injection molded products may be related to the following factors:
1. Physical factors.
When there are bubbles in […]
