Key Departments and Technical Strengths of a Manufacturer
A professional manufacturer must have highly collaborative professional departments:
a. Design and Engineering Department
Mold Design Expert: Proficient in the design of complex structures (such as large sliders, angled ejectors, hot runner systems).
CAE Mold Flow Analyst: Uses software (such as Moldflow) to simulate the filling, cooling, and shrinkage processes of plastic within the mold, predicting and resolving potential problems (such as weld lines, shrinkage, and air pockets) in advance, and optimizing mold design.This is a key indicator for measuring a manufacturer's technical level. Standardization Engineer: Establish a standard parts library for molds to improve design efficiency and interchangeability. b. Production and Processing Department: Proficient in operating large CNC machining centers for rough and finish machining of core components such as cavities and cores. Electrical Discharge Machining (EDM): Utilizing Electrical Discharge Machining (EDM) and Wire EDM to machine deep grooves, sharp corners, and complex curved surfaces that are difficult to handle with CNC machining. Precision Grinding: Ensuring the parallelism, perpendicularity, and dimensional accuracy of parts such as templates and sliders. Deep Hole Drilling: Used for machining complex cooling channels. c. Fitter and Assembly Department Senior Fitters: This is the "soul" of mold making. They are responsible for the final precision assembly, polishing, and mold fitting and debugging, relying on their rich experience to ensure smooth mold movement and tight fit. Polishing and Surface Treatment: Providing surface treatment capabilities ranging from mirror polishing to various texture etchings to meet the different appearance requirements of meter boxes. d. Quality Inspection Department Using tools such as a coordinate measuring machine (CMM), laser scanner, and precision calipers, the department conducts full-dimensional inspections of mold parts and trial mold samples to ensure they meet the drawing requirements.

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. |

| Phase 4: Sampling & Validation | 8. T1 (First Trial) & Initial Sample Report (ISIR) | • Conduct the first mold trial on an injection molding machine. • Measure and inspect T1 samples. • Provide a detailed T1 trial report with samples, pictures, and data (dimensions, short shots, etc.). | Mold Supplier | The first physical verification of the mold's performance. Identifies initial issues. |
| 9. Sample Evaluation & Engineering Changes | • Customer evaluates T1 samples for dimensions, appearance, and function. • Provide formal feedback for any required mold modifications (ECN - Engineering Change Notice). | Customer | Customer's turn to validate the part against their design and quality standards. | |
| 10. Mold Modification & Further Trials (T2, T3...) | • Implement approved ECNs. • Conduct subsequent trials (T2, T3) until samples meet all approval criteria. • Submit PPAP (Production Part Approval Process) samples if required. | Mold Supplier (with Customer feedback) | Iterative process to refine the mold until it produces acceptable parts. | |
