About CNMOULDING
Precision Injection Mold Manufacturer in China Since 1997
CNMOULDING is a China-based precision plastic injection mold manufacturer and injection molding partner, founded in 1997 and headquartered in Shanghai.
Nearly 30 years of manufacturing excellence, we have been helping global clients transform complex product ideas into stable, manufacturable, and cost-efficient injection molding solutions.
Unlike general mold suppliers, we focus on engineering-driven mold development for complex structures, high precision requirements, and stable mass production.
What We Specialize In
We do not only build molds—we engineer production stability.
Our core expertise includes:
- Complex injection mold design and manufacturing
- Core pulling and multi-slide mold systems
- Overmolding and insert molding solutions
- High-precision plastic injection molding
- Prototype to mass production transition
- Assembly-ready plastic component delivery
We are especially experienced in complex mold structures where motion, tolerance, and stability must work together under high production cycles.
Engineering Capability That Reduces Risk
Every project starts with engineering analysis—not machining.
Our process includes:
- DFM (Design for Manufacturability) analysis before tooling
- Mold flow simulation to reduce risk of defects
- Material selection support based on application requirements
- Structural optimization for moving components (core pulling systems, sliders, locks)
This engineering-first approach helps customers reduce:
- tooling modification cost
- production instability
- mass production defects
Manufacturing Strength
Our factory is equipped with advanced production systems, including:
- CNC machining centers for high-precision steel processing
- EDM and wire cutting for complex geometries
- Precision injection molding machines for stable mass production
- In-house assembly and testing systems
We maintain strict process control from mold steel selection to final trial validation.
Industries We Serve
We support both prototype development and high-volume production across industries such as:
- Automotive components
- Consumer electronics housings
- Medical device components
- Industrial equipment parts
- Household and appliance products
- Functional plastic assemblies
Our focus is on functional, structural, and precision parts—not simple cosmetic molding.
Why Customers Choose CNMOULDING
Customers choose us not only for price, but for engineering reliability and production stability.
We are trusted because we provide:
- Strong capability in complex mold structures (core pulling, multi-action systems)
- Stable tooling performance for mass production
- Competitive cost compared to US/EU suppliers (typically 30–50% lower)
- Faster mold development cycles with controlled quality
- Clear engineering communication throughout the project
We don’t just deliver molds—we reduce your production risk.
Proven Engineering Mindset
Our strength is solving difficult molding challenges, especially where standard molds fail:
- Complex internal undercuts requiring precise core pulling
- Multi-material bonding with overmolding and insert structures
- Tight tolerance functional parts requiring stable repeatability
- High-cycle production molds requiring long-term durability
We focus on function, reliability, and manufacturability—not just tooling fabrication.
Our Mission
Our mission is to become a long-term engineering manufacturing partner for global product companies.
We believe successful molding is not only about steel and machines—it is about:
design understanding + engineering control + production stability
