Three Types of Plastic moulds, Which One Is More Cost-Effective?

Plastic moulds can be divided into three categories, each of which has its advantages and disadvantages. Which of these three types of plastic moulds is more cost-effective?

(1) Large nozzle mould: Runner and gate are demoulded together with the product on the parting line. The design is the simplest, easy to process, and the cost is low. Therefore, more people use large nozzle system to operate.
 
(2) Fine nozzle mould: the runner and gate are not on the parting line, generally […]

Three Principles of Mold Material Selection

(1) Mold meets working conditions
 

Wear resistance

 
When the billet is plastic denatured in the cavity, it flows and slides along the surface of the cavity, resulting in severe friction between the surface of the cavity and the billet, which leads to the failure of the mold due to wear. So the wear resistance of materials is one of the most basic and important properties of dies.
 
Hardness is the main factor affecting wear resistance. Generally speaking, the higher the hardness of mold parts, […]

Analysis of Common Failure of Plastic Mould

Plastic mould is for plastic processing and forming. They are made of 45 steel, P20, 718 and other plastic mould steels. The failure analysis of plastic mould can better guide the research and development of mould steel. The failure modes of plastic mould are as follows:

Abrasion and Corrosion of Cavity Surface

 
1) Plastic melt flows in the cavity with a certain pressure, and solidified plastic parts come out of the mould, which will cause friction and wear on the surface of the […]

Questions and Answers on Mould Manufacturing Technology

There are many problems to be paid attention to in mould manufacturing. If you don’t know its process and key points, you should learn more about the following knowledge.
 
1) What is the most important and decisive factor in choosing die steel for mold manufacturing?
mold making
Forming method – can be selected from two basic material types.
 

A) Hot working tool steel, which can withstand relatively high temperatures during die casting, forging and extrusion.

B) Cold working tool steel, which is used for blanking and […]
