Mould Making

Custom Mold Making

As the core foundation of high-quality injection molding, custom mold making directly determines product precision, production efficiency, and long-term manufacturing costs. We provide one-stop mold making services from initial design, precision manufacturing, trial testing to after-sales maintenance, tailored to your unique product requirements and production volume needs. With years of experience serving industries including lighting fixtures, industrial structural parts, automotive, electronics, and more, we deliver durable, high-precision molds that ensure stable mass production for years to come.

What Is Mould Making

Mold making is the process of designing and manufacturing precision injection molds that shape molten plastic into your desired product form.

A well-engineered mold not only guarantees consistent part quality and tight dimensional tolerances but also optimizes cycle times, reduces material waste, and extends production lifespan. Our mold making process combines advanced CNC machining, EDM technology, and rigorous quality checks to produce molds that meet the strictest industry standards, even for complex lighting fixtures and heavy-duty industrial structural parts.

Our Mold Making Capabilities

We offer a full range of custom mold solutions to match diverse product designs and production demands, with specialized experience in molds for lighting fixtures and industrial structural parts

Standard Single-Cavity Molds

Ideal for small to medium production runs, delivering cost-effective, reliable molds for simple to moderately complex plastic parts, including basic lighting components and general industrial parts.

Multi-Cavity Molds

Designed for high-volume mass production, producing multiple identical parts in a single molding cycle to significantly boost efficiency and reduce per-unit costs, perfect for bulk lighting fixture parts and large-scale industrial components.

Hot Runner Molds

Advanced mold systems that eliminate cold runners, reduce material waste, shorten cycle times, and improve part surface quality, ideal for high-precision lighting fixtures and aesthetic industrial parts requiring smooth finishes.

Two-Shot & Overmolding Molds

Specialized molds for multi-material parts, combining hard and soft plastics or different colors in one process, perfect for complex lighting controls and ergonomic industrial structural parts.

Insert Molding Molds

Custom molds that integrate metal inserts or hardware during molding, creating reinforced, assembly-ready parts commonly used in industrial structural components and durable lighting fixtures.

High-Precision Custom Molds

Precision-engineered molds for complex, tight-tolerance parts, including intricate lighting fixture housings and heavy-duty industrial structural parts that require strict dimensional accuracy.

Professional Mold Design Services

Before manufacturing, our engineering team provides comprehensive mold design support to ensure your mold is optimized for production:

DFM (Design for Manufacturability) Analysis: Evaluate your 3D design for moldability, draft angles, wall thickness, and potential defects, providing actionable optimization suggestions.
Mold Flow Simulation: Conduct CAE analysis to predict filling, cooling, warpage, and shrinkage, identifying issues before mold fabrication to reduce trial and error.
Custom Structural Design: Tailor mold structures to your product’s unique needs, including complex undercuts, thin walls, and multi-part assemblies common in lighting and industrial applications.

Mold Materials & Hardening

We select high-quality mold steels tailored to your production volume, part complexity, and material requirements, ensuring long mold lifespan and consistent performance:

P20: Versatile pre-hardened steel, ideal for low to medium volume production of general-purpose parts, including basic lighting and industrial components.
H13 (SKD61): High-temperature, wear-resistant steel, perfect for high-volume production of engineering plastics and complex parts like industrial structural components and high-use lighting fixtures.
S136 (420SS): Corrosion-resistant, high-polish steel, suitable for clear or aesthetic parts requiring a smooth surface finish, such as transparent lighting covers.
NAK80: Polished steel for high-gloss, precision parts, ideal for decorative lighting fixtures and high-quality industrial parts.

All molds undergo strict heat treatment (hardening, tempering) to enhance hardness, wear resistance, and structural stability for long-term use.

Frequently Asked Questions

A: Lead time varies by mould complexity, typically 4–7 weeks for standard moulds, and 7–10 weeks for complex or high-precision moulds. We provide a detailed timeline after evaluating your design.

A: Yes, we offer mould modification services, including adjusting dimensions, adding features, or repairing wear to extend your mould’s lifespan.

A: Lifespan depends on mould material and production conditions. Standard moulds last 500,000–1,000,000 cycles, while hardened steel moulds for high-volume production can exceed 1,000,000 cycles.

A: Yes, we include first-article samples with every mold, tested and verified for dimensional accuracy and quality.

A: We work with you to adjust the mould as needed, providing transparent quotes for modifications and ensuring the final mould meets your requirements.

A: We take full charge of your mould development. At Hongwei, every custom mould we produce belongs entirely to you. Once mass production is done, we offer long-term mold storage onsite, or we can ship the moulds to your address on request. Our skilled engineers will assist you in inspecting and matching the moulds with your machines.
