Complete Engineering Support at Every Stage
Each engineering service is delivered by dedicated specialists with deep domain expertise. Click any card to explore the full scope of capabilities.
Product Design, Reverse Engineering & DFM
3D scanning, CAD modeling, and design-for-manufacturability analysis to optimize your parts before mold making — reducing cost, lead time, and production risk.
Rapid Prototyping & 3D Printing
Validate form, fit, and function with fast prototypes — 3D printing and CNC machining for design verification before committing to production tooling.
Injection Mold Design & Mold Building
Custom mold design and fabrication with advanced CAD/CAM, mold flow analysis, and precision machining. From single-cavity prototypes to multi-cavity production molds.
Material Selection & Engineering Support
Expert material recommendations from 50+ engineering plastics and commodity resins. Full technical support for shrinkage, warpage, and processing optimization.
Four Engineering Service Pillars
SunpeakMold’s engineering services span the complete product lifecycle. Our four specialized service areas work together seamlessly — from design optimization and DFM analysis through prototyping, mold building, and material engineering — to deliver manufacturing-ready solutions that reduce risk, control cost, and accelerate time to market.
Requirement Review
We start by understanding your product requirements, target volume, material preferences, and quality standards.
Design & DFM
Our engineers analyze your 3D models, run DFM reviews, and suggest optimizations for manufacturability and cost reduction.
Prototyping & Testing
Rapid prototypes validate form, fit, and function before committing to production tooling — minimizing risk and rework.
Mold Building & Production
We design and build precision molds, run mold trials, and scale to full production with inline quality control.
How We Work
A proven four-stage workflow that takes your idea from concept to production-ready reality — with engineering checkpoints at every stage.
Engineering Excellence at Every Stage
From initial concept to final production — our engineering team provides comprehensive support throughout your entire product development journey, ensuring quality and efficiency at every step.
