The specific material selected for a particular tool is normally determined by the mechanical properties necessary for the proper operation of the tool. These materials should be selected only after a

The steel of the injection mold is like the foundation of a house. If there is no suitable material, the mold will not meet the requirements. Today I will explain the knowledge of mold steel. Before t

①The selection of mold materials must not only meet the customer's requirements for product quality, but also consider the cost of the material and its strength within the set period. Of course, i

⑶The mold manufacturing process is also an important part of ensuring the quality of the mold. The processing method and processing accuracy in the mold manufacturing process will also affect the serv

Nowadays, the competition among manufacturing industries is becoming more and more fierce. It is very necessary for enterprises to produce high-quality products in batches in a short time. How to impr

The large diameter workpieces are fairly flexible while hot, hence they can be pulled of the thread-forming core by a simple plate as show in Fig.6.66.

Fig 2.35 illustrates another design point taht is often overlooked by engineers is the low cost of molding that can be affected if a side hole is extended to the top of the workpiece.

In the construction shown in Fig.6.65 the mandrels start to unscrew from the workplece one after the other with the use of spring-actuated clutch.
