Mold processing equipment must be carefully checked before use

1、 Before the mold processing equipment starts to work, we should check whether there are problems in each part, whether the clutch and braking equipment are normal, and whether there is lubricating oil in the gear part. After the inspection, turn on and run the machine tool for about 3 minutes. If there is no abnormality, it can be put into use.
2、 When all workers enter the work area, they should check their clothes to see if they meet […]

How is the crack of injection molded products caused

(1) In the process of processing, the pressure is too high, the speed is fast, the filling is more, and the pressure holding time is too long, resulting in large internal pressure, resulting in cracks in the die.
(2) adjust the mold opening speed and pressure during injection process to avoid the failure caused by strong drawing.
(3) Appropriately increase the mold design temperature to make the parts easy to realize demoulding, and appropriately reduce the material temperature to prevent decomposition.
(4) […]

Various factors must be considered in the design of plastic injection mold

At this stage, the competition between injection mold manufacturing industries and the cost of mold and injection molding processing are the topics that every business is very concerned about. How to reduce the cost and create economic benefits? In injection mold manufacturing, some key factors must be fully considered:
1. Injection molding cost
According to the size of machine learning equipment, how much is each beer, so as to confirm the qualifying method and number of points of corporate culture products. […]

Four problems needing attention in mold injection molding

Injection molding is an injection processing method. Compared with other processing methods, injection molding method is faster, more efficient and easier to operate. However, there are several problems that need to be paid attention to. Let’s talk about them now.
1. In order to prepare for the design stage, plastic injection molding processing should first determine what kind of injection molding should be carried out. At the beginning of injection molding, if the customer has a set of drawings designed […]

Problems in injection mold should be checked here

If you don’t pay attention to the injection mold, there will always be a variety of problems, such as cracking, including surface filiform crack, microcrack, cracking, and deformation cracking due to part sticking, runner sticking or trauma crisis according to the cracking time and application. There are several main reasons:
1. Processing:
(1) When processing the die, excessive pressure, too fast processing speed and too much blanking will lead to excessive internal pressure and fracture.
(2) Adjusting the mold opening speed and […]

What causes the wrong color after injection molding

Various problems may occur after injection molding, but these are unavoidable. Once these problems occur, they will affect the use effect of the finished products and can not meet the needs of the company. Then we should find out these problems before the production is completed and check which step has the problem, Let’s talk about the color after injection molding.
(1) Matching of injection molding machine
First, when selecting the injection molding machine, select the equipment consistent with the product. […]

The quality of finished molds is closely related to the processing mode

1. High machining precision: a pair of molds is generally composed of molds, punches and mold bases, and some can also be multi-piece assembly modules. Therefore, the combination of upper and lower molds, the combination of inserts and cavities and the combination of modules require high machining accuracy, and the dimensional accuracy of precision molds usually reaches level M.
2. Complex shape and surface: some products, such as automobile panels, aircraft parts, toys, household appliances, etc., are composed of a […]

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 precision 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 […]

These methods can help you when choosing precision mold manufacturers

At present, the rapid development of industry has gradually taken shape, and the rapid development of precision mold processing has also driven more mold processing factories. How should we choose in the face of so many precision mold processing manufacturers in the market? See below.
1. Learn knowledge in related fields, whether online or paper media collection, find out the core elements in this field and understand the basic knowledge;
2. Understand the specific local conditions of your equipment and search […]

Where does the gas generated during injection molding come from? What are the hazards?

Injection mold is a technical work, and exhaust is also a more important problem, because hot gas is easy to be generated during molding and pouring. If it is not discharged from the mold cavity in time, it is easy to affect the quality of the mold. Therefore, exhaust during injection mold is also a more strict work.
1. Source of gas
(1) Air is left in the mold cavity itself;
(2) Some raw materials contain water that has not been removed […]
