ABOUT ZECHENG
Who We Are
Zecheng Precision Mold Company is a precision-focused manufacturer based in Dongguan, China. We support customers with injection mold manufacturing, precision mold components, in-house electrode manufacturing, EDM, wire cutting, precision grinding, and CNC precision machining.
With nearly 10 years of practical manufacturing experience, we understand that high-precision parts require more than equipment alone. Drawing review, material selection, tolerance control, machining process planning, electrode preparation, grinding accuracy, and dimensional inspection all affect the final quality of each part.
Our team focuses on reliable manufacturing support for mold components, inserts, mold plates, cavities, cores, and custom machined parts. Whether the project is a new injection mold, a replacement mold component, or a precision CNC machined part, we aim to provide clear communication, practical feedback, and stable manufacturing quality. For overseas customers, we can review drawings, sample photos, and project requirements online to support clearer communication before production.
What We Focus On
Our work is centered on precision mold manufacturing and high-precision component support. From injection molds to mold inserts and custom machined parts, we focus on practical manufacturing solutions that require accuracy, stable machining quality, and reliable project communication.
Injection Mold Manufacturing
We support injection mold projects from drawing review and mold manufacturing to fitting, trial adjustment, and production-related improvement. Our focus is on mold structure, component accuracy, and practical molding performance.
Precision Mold Components
We manufacture precision mold components such as inserts, cores, cavities, sliders, mold plates, and replacement parts according to customer drawings and project requirements. Tolerance control, surface quality, and assembly fit are key points in our work.
CNC Precision Machining Support
We provide CNC machining, EDM, wire cutting, precision grinding, and in-house electrode support for mold-related parts and custom precision components. We have experience with mold steel, copper, aluminum, stainless steel, and other commonly used engineering materials.
Precision Equipment and Manufacturing Capability
Our manufacturing capability is built around the processes required for high-precision mold components and injection mold projects. From CNC machining and EDM to wire cutting, precision grinding, and dimensional inspection, each process helps us control accuracy, fitting quality, and delivery stability.
CNC Precision Machining
CNC machining supports the main shape, structure, and accuracy requirements of mold components and custom precision parts. It allows us to machine different metal materials while keeping attention on part consistency, surface quality, and key dimensional areas.
• Materials: mold steel, copper, aluminum, stainless steel
• Typical Work: mold plates, inserts, cavities, and custom machined parts
• Control Focus: machining accuracy, surface finish, and dimensional consistency
EDM and Electrode Manufacturing
EDM machining helps us process detailed mold features that are difficult to finish by conventional cutting. With in-house electrode manufacturing, we can better support cavities, ribs, corners, inserts, and other precision mold details.
• Electrode Support: in-house electrode preparation for EDM work
• Typical Work: cavities, ribs, corners, inserts, and detailed mold features
• Control Focus: electrode accuracy, discharge control, and detail consistency
Wire Cutting
Wire cutting is used for precision profiles, inserts, mold plates, and tight-tolerance areas. It is suitable for parts that require accurate shapes, clean edges, and stable dimensional control.
• Typical Work: inserts, profiles, mold plates, and precision openings
• Suitable Areas: tight-tolerance shapes and fine cutting profiles
• Control Focus: edge quality, profile accuracy, and dimensional stability
Precision Grinding
Precision grinding helps control flatness, thickness, fitting surfaces, and surface quality for mold components and related precision parts. This process is important for assembly fit and stable mold performance.
• Typical Work: inserts, plates, fitting surfaces, and precision components
• Suitable Areas: flatness, thickness, and surface control
• Control Focus: grinding accuracy, fitting quality, and part consistency
Dimensional Inspection
Dimensional inspection is used to check key sizes, fitting areas, and critical tolerances before delivery. This helps improve part consistency, assembly reliability, and overall manufacturing quality.
• Inspection Focus: key dimensions, fitting areas, and critical tolerances
• Typical Parts: mold components, inserts, plates, and custom machined parts
• Control Focus: delivery quality, assembly reliability, and dimensional confirmation
Quality and Project Control
High-precision mold components require more than accurate machining. From drawing review and process planning to key dimension control and final inspection, we focus on reducing manufacturing risks and improving part consistency before delivery.
Drawing Review
We review drawings, tolerance areas, material requirements, and surface finish needs before production.
Process Planning
We arrange machining steps according to part structure, precision requirements, and manufacturing risks.
Key Dimension Control
We focus on important dimensions, fitting surfaces, flatness, thickness, and tolerance-related areas.
Final Delivery Check
We check key sizes and project requirements before delivery to support stable assembly and use.
