Requirements for injection machine in the precision plastic molding

Injection machine is a key equipment in the plastic molding, to ensure the plastic part dimensions are in the tolerances of customer requirement, and make sure the high rate of qualified parts.

There have 2 index to show injection machine performances

• Error rate of plastic part dimensions repeat

• Error rate of plastic part weight repeat

For high precision injection machine, machine also need own the capacity for high injection pressure and high injection speed, fix mold system also need stiff enough and enough precision to fix mold
