Frequently Asked Questions
Everything about overmolding services.
For Engineers
What materials can be overmolded?
ABS/TPE, PC/silicone, PP/TPE, nylon/soft-touch, and custom combinations with compatible bonding.
What tolerances can be achieved?
Standard tolerances ±0.05mm for features, with tighter tolerances available for critical dimensions.
How does overmolding affect cycle time?
Cycle times are slightly longer than standard molding but still efficient compared to secondary assembly.
For Procurement
What's the minimum order quantity?
No minimum for production. From prototype quantities to millions of units.
How does pricing compare to assembly?
Overmolding eliminates secondary assembly costs, often resulting in lower total part cost.
What's the lead time for tooling?
Specialized overmold tooling typically takes 10-14 weeks. Prototype tooling available in 4-6 weeks.
For Decision Makers
Why choose overmolding?
Single-step production, reduced assembly costs, improved part aesthetics, and better ergonomics.
What's the ROI?
Typically 20-40% savings vs. secondary assembly with improved quality and faster delivery.
Can we qualify multiple parts?
Yes, we can overmold multiple variants in the same family with flexible mold designs.
Frequently Asked Questions
Quick answers to common questions from engineers, procurement, and decision makers
For Engineers
What tolerances can you achieve for complex geometries?
We achieve tolerances up to ±0.005mm on critical features using 5-axis CNC and EDM processing. Our DFM analysis helps optimize designs for manufacturability.
Do you provide mold flow analysis before production?
Yes, comprehensive mold flow analysis is included free with every project. We simulate filling patterns, identify potential defects, and optimize gate locations.
What materials do you recommend for high-stress applications?
We offer ABS, PC, POM, Nylon, PP, and engineering resins. For high-stress parts, we recommend glass-filled or carbon-filled polymers with reinforced fillers.
For Procurements
What are your minimum order quantities?
No minimums! We support startups and small businesses with orders from 1 piece to millions. Volume discounts available for larger orders.
How fast can you deliver production parts?
Prototype molds in 7-15 days. Production parts in 2-3 weeks after mold approval. Express services available for urgent projects.
Do you offer competitive pricing for high volumes?
Yes! Our pricing scales with volume. Contact us for a customized quote. We beat OEM pricing by 20-40% while maintaining premium quality.
For Decision Makers
Why choose CoreLMould over other suppliers?
15+ years experience, ISO 9001 certified, zero-defect culture, 24-hour quote response, and a dedicated team committed to your success.
How do you ensure quality consistency across batches?
