While both steel and aluminum are usually suitable for a broad range of standard injection molding resins steel can offer an advantage if youre working with more complex or advanced formulations such as those reinforced with glass fiber or other additives. Other materials include aluminum and epoxy-like composite materials which work well for low-volume projects. A hands down steel choice for Toth MoldDie Inc.

2 form follows function a bÖhler tool steel is the optimum answer to any application in the manufacture of plastic mould parts meeting the increased epectations of users as regards shape function esthetics product quality and durability. The major differences are. Of plastic injection mold steel.

Steel Injection Molds Have the Ability to Make Complex Parts. It belongs to plastic mould steel. Many of our competitors on the other hand make their molds out of aluminum.

Injection Molds Tool can be manufactured either by. P-20 is the first choice in most cases when using plastics without abrasive additives but as I mentioned earlier unless its for very low-volume use you will need to protect the steel against erosion with a coating or surface hardening. There are several advantages of using steel injection molding over aluminum injection molding which we will explain here.

S7 is a very durable impact-resistant tool steel material that can be hardened up to 56 RC. Normally for the small quantities plastic injection mold is okay to use this steel. The standard porous steel part ie.

Steel molds have more finishing options for surface texture than an aluminum mold. If you have a specific texture needed for customer. There is also a grade P-20 HH which is a high hard version getting up to 38 RC.

In general steel cost more to construct but their longer lifespan will offset the higher initial cost over a higher number of parts made before wearing out. DxHigh Carbon High Chromium Steel. This is a pre-hard steel which is usually 30-32 RC.

Advantages of Steel Over Aluminum Molds. Steel has the ability to hold tighter tolerances over a longer period of time or for a larger number of molding shots. Ramax heat-treating mold steel is used to manufacture a mold for low to medium polished injection-molded plastic parts.

For steel that does not require heat treating is P-20. Inserted in a plastic injection mold to help solve ventilation issues. Each steel type has limitations.

Therefore injection mold steel selection is directly influenced by the design of your medical injection mold and the plastic material of your device. With sample processing technic it is commonly used in the industry of mold. UDDEHOLM PREHARDENED MOULD AND HOLDER STEEL Uddeholm Impax Supreme AISI P20 modified which is refined by the vacuum degassing technique offers good machinability and homogeneity excellent polishability and.

Part complexity can be increased with intricate designs and multiple inserts. The round bar usually costs no more than 100 RMB and the cheapest costs only 10 or 20 RMB. Mould design 6 Mouldmaking 10 Moulding 14 Moulding methods Injection moulding 17 Compression moulding 17 Blow moulding 18 Extrusion 18 The same quality and service available worldwide 20 Product programme for plastic moulding 21 Chemical composition and properties 22 Mould steel selection General recommendations 23.

It is usually applied in small quantities as inserts with standard parts available on the market. It has a lower heat transfer ability as compared to other metals. Steel molds are easier to modify if you have design changes so theyre a better choice if theres a good chance your part may have design revisions.

For the majority of the plastics being injection molded I recommend the steel not be heat treated above 58 RC. Typically plastic injection molds are manufactured from either heat-treated tool steel or pre-hardened steel. Injection Molds are constructed from hardened steel pre- hardened steel aluminum beryllium-copper alloy.

Produce injection molded parts. NAK80 is suitable for use in the plastic injection mold.
