Custom Plastic Molding Parts Service

For such plastic Mold Parts as Guide Sleeve, the selection of material depends on the function of the parts, the pressure involved, temperature, expected life, and most importantly cost.

1. Tool steel

Tool steel is the most widely used material for plastic molds, while this material is characterized by the ability to resist wear, its hardness is sufficient to provide Processing is carried out for a long time, but the shape of the mold remains stable. Among them, the conveniently located P20, H13, and S136 are very typical cases.

2. Aluminum alloys

Aluminum alloys are applied in large molds or molds wherein rapid cooling is feasible, because of their light weight and good heat conductivity like AlSi9Cu3. It has improved machinability but is highly inferior to steel in terms of corrosion as well as wear rates.

3. Stainless steel

Austenitic Stainless Steel like 316L has good corrosion and good to fair wear properties and is ideal for manufacturing components in acidic, alkaline conditions or when the product needs to be highly clean.

4. Carbon steel

Carbon steel has low strength in terms of hardness and abrasion and is cheap, this type of steel is appropriate to be used in small and simple molds or test molds.

5. Specialty alloys

For special needs special materials like nickel-based sixty materials might also be used, these are materials that are capable of withstand extreme temperature or corrosion but they will cost a lot of money.

The type of material to be used in the plastic mold parts requires consideration of the usage intensity of the mold, the working conditions, product specification, and cost factor. In use, the most typical is the tool steel as it offers the closest match between performance and cost. However, for activities with certain demands, other materials may also become preferable at the same time.
