Insert Molding Services
Metal and other inserts molded directly into plastic. Strong, integrated assemblies in one production step.
Insert Molding Applications
Types of inserts and applications for insert molding.
Threaded Inserts
Strong threads for repeated assembly, brass or steel inserts for plastic parts.
Bushings & Bearings
Self-lubricating, metal-backed, and wear surfaces for moving applications.
Electrical Contacts
Terminals, connectors, and conductive elements for electrical applications.
Insert Molding Benefits
Advantages of molding inserts directly into plastic parts.
Strong Assembly
Inserts are permanently locked in place by the plastic, creating strong assemblies.
Reduced Labor
Eliminate secondary insertion operations and manual assembly steps.
Precision Placement
Inserts are placed with high precision in the mold, ensuring accurate positioning.
Cost Savings
Lower total cost through reduced assembly and improved production efficiency.
Design Flexibility
Combine plastic and metal properties in ways not possible with separate parts.
Reliability
Consistent quality and reduced risk of insert failure compared to post-molding insertion.

Frequently Asked Questions
Everything about insert molding services.
For Engineers
What insert materials work best?
Brass, steel, stainless steel, aluminum, and copper inserts work well with compatible plastic materials.
What tolerances are achievable?
Insert position tolerances of ±0.05mm typical, with thread quality to Class 6H or better.
How are inserts placed?
Manual or automated insertion in the mold. We use precision fixtures for high-volume production.
For Procurement
What's the minimum order quantity?
No minimum for production. From prototype quantities to millions of units.
How does pricing compare?
Insert molding costs more upfront but eliminates post-molding insertion labor costs.
What's the lead time for tooling?
Insert molding tooling typically takes 8-12 weeks. Prototype tooling available in 4-6 weeks.
For Decision Makers
Why choose insert molding?
Stronger assemblies, reduced labor, improved precision, and lower total cost for high volumes.
What's the ROI?
Typically 30-50% savings vs. post-molding insertion with improved quality and consistency.
Can we qualify multiple inserts?
Yes, family molds can accommodate multiple insert configurations for product families.
