Core Mould Manufacturing Service Process
Requirement Analysis & Design
Collaborate with clients to define product needs, conduct DFM analysis, mould structure design, and cost evaluation to deliver a feasible mould solution.
Precision Machining & Component Fabrication
Utilize CNC machining centers, EDM, wire-cut EDM, and grinding machines to produce mould cores, cavities, and components with tight tolerances.
Mould Assembly, Testing & Validation
Complete mould assembly, fitting, and precision adjustment, then conduct trial runs to verify part quality and optimize moulding parameters.
Delivery, Acceptance & After-Sales Support
Deliver qualified moulds with inspection and trial reports, provide technical guidance, and offer ongoing maintenance and modification services.
Types of Injection Moulds We Manufacture
Choosing the right injection mould is key to your production efficiency, product quality and cost. We provide professional mould solutions for different products and production needs.
Single‑Cavity Moulds
One cavity, one part per cycle. Simple structure, low cost. Ideal for prototype making, sample testing and small‑batch production.
Multi‑Cavity Moulds
Multiple cavities in one mould. Produce many parts at the same time. High efficiency, low unit cost. Perfect for mass production.
Two‑Shot Moulds
Two materials moulded in one step. Make soft‑hard combined products. Stable quality, widely used for daily goods, auto parts and handles.
Hot Runner Moulds
No material waste, fast cycle. Smooth product surface, no need to trim. Best for high‑precision and high‑volume plastic parts.
Thread Unscrewing Moulds
Automatic demolding for threaded parts like caps, bottles and connectors. Stable, reliable and suitable for automatic production lines.
Custom Special Moulds
Custom design for complex products: auto parts, daily items, electronics, industrial parts. High precision, long service life, fully tailored to your needs.
Successful Mould Solutions
At Hongmei Mould, we excel in delivering high-precision, cost-effective injection mould solutions tailored for diverse industrial needs.
Result: 800,000+ shot lifespan, consistent appearance, suitable for brand production
Advanced Mould Manufacturing Equipment
Our mould manufacturing is supported by a full set of high-precision processing equipment, which guarantees the precision and efficiency of mold production. The equipment we use includes:
CNC Machining Centers
Electrical Discharge Machines (EDM)
CNC Lathe
Grinding Machines
Mould Material Selection
Mould materials are the fundamental foundation determining mould lifespan, forming precision, and product quality. We scientifically select specialized steels with high hardness, wear resistance, and machinability based on product material, production volume, and operating conditions.
P20 / 718H:
Pre-hardened mould steel, easy polishing & corrosion resistance，Ideal for medium-to-long run molds of automotive interior/exterior & home appliance housings.
S136 / 420:
Corrosion-resistant mirror steel, high polishability，Suitable for transparent parts, medical parts & food-contact moulds
H13 / SKD61
Hot-work mould steel, high temperature & fatigue resistance，For high-volume, high-hardness plastic or die-casting moulds
Mould Manufacturing Flowchart
Mould manufacturing is a systematic and high-precision processing procedure. Through scientific and reasonable technological processes,
it realizes the complete transformation from design drawings to qualified molds, providing core guarantee for mass production of products.
Mould materials are the fundamental foundation determining mould lifespan, forming precision, and product quality. We scientifically select specialized steels with high hardness, wear resistance, and machinability based on product material, production volume, and operating conditions.
Mirror Polishing
Ultra-smooth finish with Ra ≤ 0.05μm, delivering high clarity and gloss for transparent parts and premium cosmetic surfaces.
Sand Blasting
Uniform matte finish that eliminates tool marks and provides a consistent appearance for mold cavities.
Mold Texturing
Customizable textures to enhance grip, hide defects, and achieve premium aesthetic effects for plastic parts.
Nitriding
Thermochemical surface hardening that increases wear resistance and reduces friction for high-volume production molds.
Mould Measuring & Insepction
Such as:three coordinate detector image projector, Blue-ray scanner sclerometer, mold temperature tester, hardness-testing device. Spectrum analyzer, flow in cooling water, discharge device and air transfer test table etc.
