As a leading precision mold manufacturer in Dongguan, China, Dongguan Yize Mould Co., Ltd. (Yize Mould) has refined its plastic mold processing workflow over two decades of industrial excellence. Our end-to-end process is engineered for precision, repeatability, and rapid turnaround—aligned with international standards and tailored for global clients in automotive, medical, and electronics industries.
Core Processing Workflow
Plastic mold manufacturing is a synchronized, multi-stage engineering discipline. At Yize Mould, we follow a structured, closed-loop methodology:
- Design & DFM Analysis: Leveraging client 3D models or physical samples, we conduct Design for Manufacturability (DFM) evaluations to optimize parting lines, gate systems, cooling channels, and draft angles—ensuring compliance with GB, JIS, DIN, and AISI standards.
- Material Preparation & Rough Machining: High-grade mold steels (P20, 718H, H13) are selected and pre-treated before rough milling and planing to achieve stable blank geometry with controlled machining allowances.
- Precision Machining & Special Processes: Complex cavities are machined using 5-axis CNC systems for sub-micron contour accuracy. Deep features and fine textures are finished via EDM (Electrical Discharge Machining), achieving tolerances of ±0.005mm. Critical surfaces undergo mirror polishing to meet Ra≤0.025μm standards, suitable for optical and medical-grade components.
- Assembly, Debugging & Trial Molding: Assembly occurs in temperature-controlled environments with guide pin/ bushing clearances held to ≤0.01mm. Cooling circuits and ejection systems are functionally validated through iterative injection trials, verifying shrinkage, weld lines, and dimensional consistency.
- Delivery & Post-Sales Support: Upon client approval, full technical documentation and maintenance protocols are delivered. We offer global remote engineering support and rapid modification services to ensure long-term production stability.
Dongguan’s Strategic Manufacturing Advantage
Located in the heart of China’s mold manufacturing cluster, Yize Mould benefits from a dense ecosystem of high-quality heat treatment providers, metrology labs, and logistics networks. This enables us to deliver complex molds in 15–25 days—significantly faster than the industry average of 25–40 days—while maintaining uncompromising quality.
FAQ – Frequently Asked Questions
Q1: What is the typical lead time for plastic mold production?
A: Standard molds require 15–25 days from design to trial. Simple two-plate molds can be completed in 12 days, while complex molds with multiple slides, hot runners, or side actions typically take 25–40 days. Yize Mould achieves over 95% on-time delivery through parallel engineering and standardized workflows.
Q2: How do you ensure machining accuracy?
A: We maintain a closed-loop quality system using 5-axis CNC, slow-wire EDM, and CMM measurement. All critical dimensions are controlled within ±0.001mm, with coaxiality ≤0.002mm and straightness ≤0.002mm/300mm. Stress relief and deformation compensation are applied after heat treatment to guarantee dimensional stability over the mold’s lifecycle.
Q3: How do you maintain high mold yield rates?
A: Yield is driven by process control. We implement source inspection of raw materials, standardized machining parameters, and full traceability of trial data. For medical and electronics clients, we operate in Class 1000 cleanrooms with automated assembly lines to ensure product cleanliness and consistency—resulting in a client retention rate consistently above 99%.
