These six requirements for the purchase of plastic molds can not be ignored

Plastic mold is the abbreviation of a combined mold used for compression molding, extrusion, injection, blow molding and low foaming molding. A series of plastic parts with different shapes and sizes can be processed by the coordinated change of punch, die and auxiliary forming system. In order to meet the needs of molded parts, we need to pay attention to some matters when selecting plastic molds, and put forward corresponding requirements. Now choose a more suitable plastic mold to […]

Three principles of mold material selection

（1） The mold meets the requirements of working conditions
1. Wear resistance
When the blank is plastically denatured in the mold cavity, it flows and slides along the cavity surface, resulting in severe friction between the cavity surface and the blank, resulting in the failure of the mold due to wear. Therefore, the wear resistance of materials is one of the most basic and important properties of molds.
Hardness is the main factor affecting wear resistance. In general, the higher the hardness […]

Temperature control of plastic mold processing and injection molding

Temperature control plays a very important role in plastic mold processing and injection molding. It can decide whether the product is good or bad. In a big way, even if you make it to the customer, you will lose the customer’s trust in you and cause losses to the company. In a small way, it doesn’t matter. It’s a big deal to redo. Don’t do this, but you should remember that these are actually a waste of the company’s […]

Analysis on strength performance, thermal fatigue resistance and bite resistance of mold steel

1. Strength performance
(1) Hardness
Hardness is the main technical index of mold steel. In order to keep its shape and size unchanged under the action of high stress, the die must have high enough hardness. The hardness of cold working mold steel is generally maintained at about HRC60 at room temperature. According to its working conditions, hot working mold steel is generally required to be maintained in the range of hrc40 ~ 55.
For the same steel, within a certain range […]

What are the main components of injection mold processing

Injection mold is a compact tool, which has irregular shape and bears the expansion force of blank. Therefore, there are high requirements for structural strength, stiffness, hardness, roughness and machining accuracy. The increase of injection mold is one of the most important symbols of the degree of mechanical manufacturing.
After a long time of operation, the injection mold needs to be polished. The polished edge must be demagnetized without magnetism, otherwise it is easy to cause blockage. The company shall […]

What do you know about the driving mode of injection mold

The products processed by injection mold have long been seen everywhere in our lives, but in fact, many people don’t know much about injection mold processing. This article will take you to understand several ways of injection mold processing drive:
The drive and driving force for the processing and movement of injection mold are provided by the power of processing machine tools and equipment through the transmission mechanism.
Electromechanical transmission: for example, punching press, friction press, roll forging machinery, etc., the […]

Injection molding actually has several methods

In fact, injection molding is also a processing procedure, and many supplies have to go through this procedure, because it is mainly to further improve the quality and safety level of tools, so that customers can buy and use them at ease. Injection molding procedures are also divided into many kinds. We only briefly list the following.
Compression injection molding: (compression molding) is an advanced form of traditional injection molding.
Advantages: it can increase the flow ratio of injection molded parts; […]

How to solve the surface defects when processing products

Generally, in mold processing, if we need to use injection molding equipment to process the product surface, there will be large and small defects. Generally, these defects will appear in the gate position, which belongs to the starting position of mold processing, so these two positions are prone to problems, so we need to find ways to eliminate these defects, so that the display effect will be improved.
Dark spot defects and subtle defects will appear near the gate, which […]

What are the reasons for material bending in die processing

In the process of mold processing and customization, there may be a series of situations. In fact, one of the phenomena we will face is the bending deformation of injection mold processing. Then, in the whole processing process, in addition to considering the final requirements or installation, we should also consider the performance of tooling and equipment. In this case, it is necessary to consider more injection mold processing processes. Why is there bending during mold processing?
Mould
In the process […]

How is it caused that the injection mold is easy to be damaged in the molding stage

Injection mold refers to processing a mold in the form of injection molding, but if this process is not well grasped, it is easy to damage the material; And if the injection mold tools are used for a long time without careful maintenance, they are prone to damage, which will also cause losses to the company. What are the reasons for the damage?
So why is the injection mold damaged? We all know that when assembling the injection mold, there […]
