Question 1

What mold materials are best for two shot injection molding?

Accepted Answer

Molds are made from high-grade tool steels like P20, H13, and stainless steel to handle high temperatures and pressures.

Question 2

What is the lead time for a two shot injection molding project?

Accepted Answer

It typically takes 4 to 12 weeks, depending on mold complexity, material selection, and production volume.

Question 3

Can recycled plastics be used in two shot molding?

Accepted Answer

Yes, but with limitations. Recycled thermoplastics can be used, but material consistency and bonding strength must be carefully controlled.

Question 4

What is the maximum part size for two shot molding?

Accepted Answer

The maximum size depends on machine clamping force (50 to 3,000+ tons) and part design complexity.

Question 5

How do I ensure material compatibility in two shot molding?

Accepted Answer

Selecting materials with similar melting points, good adhesion properties, and proper chemical compatibility is key.
