Household appliance molds
1. Core Manufacturing Capabilities: Integration of Precision and Efficiency
We are committed to integrating "high precision" into the entire process of mold manufacturing:
Digital design and simulation analysis:
We fully apply CAD/CAE/CAM systems to conduct moldflow analysis (Moldflow), structural stress analysis and cooling optimization in the early stages of product development to accurately predict and resolve potential defects such as sink marks, warpage, weld marks, etc., ensuring the scientificity and reliability of mold design from the source. Ultra-precision machining and testing: We utilize advanced equipment such as high-speed CNC machining centers, precision wire-cut machining, mirror EDM, and five-axis linkage to ensure mold cavity accuracy within ±0.005mm. We achieve mirror polishing (Ra < 0.1μm) or fine-grained etching on key components, giving our home appliances a premium look and feel.
Equipped with three-coordinate measuring machines, laser scanners, etc., we implement full-process precision monitoring to ensure that each set of molds perfectly matches the digital model.
Micro-precision molds: Used for tiny structures such as home appliance buttons, light guides, and precision connectors.

A: Of course. We always produce and provide initial sample parts (T1) from the new mold for your approval. This allows you to verify dimensions, appearance, and function before we proceed to mass production.
A: Our molds are designed to process various common plastics used in appliances, including ABS, PP, PS, PC, and PA (Nylon). We select the appropriate mold steel and design the mold structure based on your specific material choice.
A: We offer comprehensive after-sales support. This includes providing detailed mold maintenance guidelines and offering repair and modification services to ensure your mold maintains peak performance and a long service life, maximizing your return on investment.
A: Our key differentiator is our dual specialization. We are not just general mold makers; we have deep, specific expertise in both the highly technical Cold Fan category and the broad Home Appliance market. This focus allows us to provide superior engineering solutions and value for our clients in these sectors.
A: We take IP protection extremely seriously. We are willing to sign a strict Non-Disclosure Agreement (NDA) before any project discussion. All your designs, drawings, and data are treated with the utmost confidentiality and are never shared with any third party.
Standard Process for Ordering Injection Molds：
| Phase | Stage | Key Activities / Deliverables | Responsible Party | Purpose & Notes |
|---|---|---|---|---|
| Phase 1: Project Initiation & Feasibility | 1. RFQ (Request for Quotation) | • Provide detailed product design (3D CAD, 2D drawings). • Specify requirements: material, annual volume, target part cost, lead time. | Customer | Establishes the project baseline and allows the mold supplier to provide an accurate quotation. |
| 2. Design for Manufacturability (DFM) Review | • Mold supplier analyzes the product design for moldability. • Provides DFM report with suggestions on draft angles, wall thickness, gate locations, shrinkage, etc. | Mold Supplier (with Customer approval) | Critical for avoiding costly mold modifications later. Ensures the part is optimized for injection molding. | |
| 3. Quotation & Commercial Agreement | • Submit a detailed quotation covering mold cost, payment terms, and project timeline. • Negotiate and sign a purchase order (PO) and/or contract. | Mold Supplier & Customer | Formalizes the commercial agreement and project scope. | |
| Phase 2: Engineering & Design | 4. Mold Design Finalization | • Create detailed mold flow analysis. • Finalize mold design (2D layout, 3D model) including: cavity/core, slider/lifter mechanisms, cooling system, ejection system. • Customer approves final mold design. | Mold Supplier (with Customer approval) | The mold design is the blueprint for manufacturing. Approval at this stage is crucial. |
| 5. Material & Component Sourcing | • Procure approved mold base, steel (e.g., P20, H13, Stainless for corrosive materials), and standard components (hot runners, ejector pins, etc.). | Mold Supplier | Using quality materials is essential for mold life and performance, especially for high-volume家电 (home appliances). | |
