Raw material purchasing process of plastic mould

In order to maintain stable quality and high production life of plastic mold, the importance of the quality of steel used is self-evident. The quality of steel directly affects the life of plastic mold quality. Therefore, in the selection of plastic mold steel, we need to consider the mold steel material suitable for customer demand.
In general, if the customer requires a high output, the steel with higher hardness must be selected, otherwise it is easy to wear and tear, […]

What causes short shot of plastic mold in injection molding?

Short shot refers to the phenomenon that the cavity of plastic mold is not completely filled due to the insufficient fluidity of plastic, resulting in incomplete plastic products. The main reason is improper injection pressure and speed (including excessive pressure loss caused by resistance), which is mainly affected by the following aspects:
 
1、 Injection molding machine
(1) Insufficient injection molding capacity – this is caused by the high capacity of the injection molding machine, which may also be caused by insufficient […]

How to ensure the precision of injection parts in high precision injection mold factory?

The characteristics of high precision injection molding are as follows:
The specification of injection molded parts has high precision and small dimensional tolerance.
To ensure the requirements of high precision injection molding, the necessary standards are as follows:
1. Good die material, enough stiffness, die specification accuracy, smoothness and precision positioning between the templates should be high.
2. High precision injection molding machine should be selected.
3. High precision injection molding process should be selected.
4. Plastic materials suitable for high precision injection molding process […]

Personalized customization of plastic mold has become the development trend

Engineers at a plastic mold manufacturing company say they are first tier suppliers to large auto parts companies, but since last year, they have received more and more customized orders for small plastic molds. When people think that there are more and more small customized products in the Bluetooth headset plastic mold industry, even the hardware industry has this trend.
In short, the plastic mold manufacturing industry has been connected with the Internet. In the early days of the absence […]

Solutions to common defects in TPE injection molding

The appearance of various irregular lines on the surface of TPE products, which affect the appearance quality of products, must be common. Various texture defects on the surface of TPE products can be divided into the following two situations according to their causes:
 
1. Injection flow mark
Injection flow mark is the trace of molten metal flow, which takes the gate as the center and presents stripe shape. Flow mark is the boundary between the material injected into the mold cavity […]

Five techniques for optimizing injection molding process

What does “optimizing” the injection molding process mean? Generally speaking, this means that the process must be carefully checked to achieve valuable and effective process objectives. Let’s take a look at five techniques for doing this.
1. Quality control by manufacturing samples.
Of course, quality control is the key part of the whole molding production process, which is usually carried out in the later stage of production, while the quality control of sample parts is different. In order to pursue the […]

How to achieve higher product performance tolerance in injection mold processing

What is the tolerance range?
Tolerance is an acceptable limit of variation: including physical properties or dimensions.
In the process of injection mold processing, the size of plastic parts depends on many variables, and it is not necessarily processed into accurate size like other manufacturing processes. The factors affecting the size change of plastic parts include: material, performance, design, machine and production process.
In the injection mold design stage, uncertainty of mold tolerance can lead to incorrect matching, product or function failure, […]

The automobile industry has developed rapidly in the past ten years, and more and more new products have entered the market, such as new energy vehicles. A large number of automatic parts are made of plastic. As a new material of automobile parts, plastic parts can reduce the weight of automobile and save energy, so they are widely used in automobile industry. This means that a large number of plastic injection molds are needed to produce the required plastic […]

Injection molding process of precision mould for metal insert

What is metal forming?
Metal insert molding is to insert metal objects in the process of plastic injection molding. The melting material and the insert are combined to form an integrated product forming process.
Why metal insert molding?
1. Injection molding materials: plastic materials and other materials, such as metal inserts, pins, copper nuts, iron sheets, steel balls, fibers and other materials for injection molding.
2. Vertical injection mold structure: 1 front mold, 2 back mold
3. Advantages of vertical multi-material injection molding: the […]
