Making prototype molds is as much an art as it is a science and there are a range of feasible mold types that can be utilized in order to develop prototype parts. A few of the typical variants include the following:MUD (Master Unit Die) Molds:This type of mold includes a standard injection molding frame that utilizes a number of inserts in order to define the shape of the internal cavity (and thus...

The function of an ejector sleeve is similar to that of an ejector blade,in that both are typically used to push on a vertical section of the molded part.The design of the ejector sleeve varies significantly,however,since it is a hollow cylinder that slides along a fixed core pin to provide an ejection force at the bottom surface of a plastic injection molded boss.Ejector sleeves are very effectiv...

Molding machine operations should be able to operate the injection mold with minimal information.The number of external connections should be kept to a minimum,and preferably two(one inlet and one outlet)per mold half.If more than two connections are required,then the connections should be labeled”in”and”out”to help the operator avoid forming a dead circuit.To avoid damage to the cooling system,al...

How to choose good material for your mold? 1.For the appearance of product quality requirements, mold longevity, mass production, and the molding parts material selection are as follows: a) high-grade imported steel cavity to be high mirror polishing performance, such as 718 (P20+Ni), NAK80 (P21), are pre hardened state, without heat treatment. B) core can be used in low-grade im...

The plastic injection mold material mainly depends upon the annual shot quantity requirement. But it also depends upon part design and part plastic material.For shot quantity requirements of less than 500,000 prehardened tool steel (called P20) is most commonly used for cores and cavities and the mould base.Although mild steel could also be used for the injection mould base as well.This steel is c...

Reasonable selection of mold material and correct heat treatment process are the key toensure the life of die. Take stamping mold for example,how should we choose the material for stamping mold parts in mold processing? In short,we should take the following conditions into consideration:1.Batch production2.Material property3.Lower production cost4.Developing special die steel5.Considering the pro...

As part of the mold base and materials procurement process.the various types of metals must also be selected.Just as there are many different plastics suitable for injection molding,there are many ferrous and non-ferrous metals that are suitable for use in injection molds. Some of the more common metals and their properties are provided in Appendix B.Of all these metals,AISI P20...

We can use any type of steel appointed by customer or popular in the market.Such as P20, 718, 8407, NAK80, H13, S136, DIN 1.2738, DIN 1.2344, etc.

What is the normal mold steel for injection mold and what is their usages?P20 - general requirements of the plastic mold steel, produced in the United States, can be electric erosion operation, the factory state pre-hardened HB270-300, quenching hardness HRC52.718 - high standard plastic injection mold steel, produced in Sweden, suitable for electric erosion operation, the factory state pre-harden...

718H injection mould steel is one of the mould steel.718H mould steel has 40%s carbon element.718H steel plate like other injection mould steel plate.718H steel plate often used in the machinery, radio instrumentation, electrical, electronics and other industrial sectors in the manufacturing part of the main processing tools. 718H mould steel Application:718H mould steel is the machinery, radio in...

There are #45, p20, 718, 2738, H13, S136 6 different steels for mould making, different price for different character and quality. And P20 is the cheapest steel for mould making, Today, We discuss P20 at first.P-20 mold steel polishes out smother than tool steel which help with the release of molded plastic parts. P-20 is mold quality alloy steel supplied in the prehardened condition. Special m...
