What is the reason why injection molding is widely used

In daily life, the toys we buy for our children, or bottles, containers and other materials need to use injection molding technology. More products we don’t know are also manufactured and processed by injection molding industry. Why do so many products use injection molding? Because it has several advantages.
1. Suitable for producing precision products
One of the main advantages of plastic injection molding technology is that it can design a complex plastic precision parts and components through easy teaching. Compared […]

Five elements in plastic mould

1. Parting line: the contact surface between the plastic mold and the punch when it is closed. The selection of its position and form is affected by product shape and appearance, wall thickness, forming method, post-treatment process, die type and structure, demoulding method and forming machine structure.
2. Structural parts: sliding block, inclined top and straight top of complex mold. The design of structural parts is very critical, which is related to product life, processing cycle, cost, product quality and […]

Pay special attention when injecting medical molds

There are some points that need to be paid attention to when injecting medical molds. Because medical molds are precision types, we should make all the dimensions better so that there will be no great changes in the molds. For injection mold engineers, it is very important to grasp the dimensions of injection parts and molds according to the design drawings, manufacturing process The molding process is controlled from three aspects.
In addition, we also need to consider the appropriate […]

Do you know the characteristics of mold processing

Mold processing industry is developing rapidly. Now many things are made of mold processing. This article takes you to understand its characteristics.
1. The technical accuracy of mold processing can be high. The mold is generally composed of female mold, male mold and mold base system, and some may also be multi piece assembly design modules. Therefore, the combination of upper and lower dies, the combination of insert and cavity, and the combination between module functions all require high machining […]

The effect of injection molding is very satisfactory

1. High efficiency
Injection molding technology is very convenient and fast, and can realize mass production. Why? Because injection molding is to add some materials to the barrel for heating, inject the materials into the mold cavity after melting, and then wait for cooling. After cooling, the details will be the finished product, so the efficiency of injection molding is still very high.
2. High strength
Glass fiber additives are used in plastic materials. These highly engineered composite plastics have strong durability […]

Why auxiliary equipment is used 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 each processing process. 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 […]

The quality of the finished mold can be seen during processing

1. High requirements for mold processing accuracy: a finished mold is composed of many parts, and some molds are formed through complex splicing, so the processing accuracy of each splicing part needs to be emphasized in the mold processing process, otherwise the upper and lower molds and cavities cannot be combined.
2. The mold contour is complex: the surface shape of some products, such as automobile panels, aircraft parts, toys and household appliances, forms a combination of multiple curved surfaces. […]

There will be no problems in the process of injection molding as long as you pay a little attention

Injection mold needs to pay attention to many problems in the production process in order to produce qualified products.
1. In injection mold processing, due to the different shrinkage coefficients of various materials, the mold must have a reasonable shrinkage rate.
2. The injection mold should have enough rigidity during processing, otherwise it will deform and cause “flash” during mold closing and pressure maintaining.
3. The cooling (water passage) in the processing of injection mold is related to product quality, size, shape, […]

How to check and accept the injection mold

In order to ensure that the injection molding mold can meet the standard, it is necessary to consider the application regulations and design scheme, and ensure its service life. When it is normally completed and put into operation, it is necessary to ensure the quality of the mold specification from the aspects of product quality, mold structure and injection molding process regulations. On the other hand, the transformation of household appliances has also driven the in-depth development of household […]

Pay attention to speed and time when machining the mold

On the die steel with the same surface roughness, the machining speed generated by relative electric pulse during electrode loss is an important factor index to measure the performance of electric pulse machining and machine tool technology products. Generally, in this case, the manufacturer will provide its own processing current to ensure that we can effectively realize the processing speed when the mold is in the processing state. However, in the actual processing design process of life, the processing […]
