المزايا الأساسية

1. Factory-Parameter Matching, Ready-to-Use After Delivery

The gate position, runner size and exhaust structure are fully designed according to Haifeng low-pressure foaming machine parameters, adapted to the direct injection process. No repeated debugging is required after delivery, greatly reducing trial production material waste and project launch cycle.

2. One-Piece Injection Molding, Firm Bonding & No Delamination

The upper is directly placed into the mold cavity, and the sole material is injected onto the upper to realize dual physical and chemical bonding. It eliminates the traditional gluing process, completely solves the problem of sole delamination, and significantly improves the peeling strength of finished products to meet safety shoe standards.

3. Strict Quality Control From Premium Cooperative Manufacturers

We cooperate with mature professional mold factories in the industry, implementing full-process quality control from material selection, CNC precision machining to surface hardening treatment, ensuring every set of molds meets precision, wear resistance and service life standards.

4. One-Stop Procurement, Reduced Coordination Cost

We provide unified quotation, delivery and acceptance for foaming machines and supporting molds. You don’t need to coordinate with equipment factory and mold factory separately, which greatly shortens project launch cycle and reduces multi-party communication costs.

5. Optimized Runner & Exhaust, Stable Molding Quality

Combined with rich PU foaming process experience, we optimize the runner and exhaust structure of the mold. Finished soles have uniform internal density, no visible pores, high surface smoothness and less flash, reducing post-processing labor costs.

6. Unified After-Sales Support, Fast Problem Response

Both equipment and molds are supported by Haifeng technical team. When production problems occur, you don’t need to communicate with multiple suppliers. We provide one-stop troubleshooting to minimize downtime loss. Custom mold development according to your shoe drawings, hardness and pattern requirements is also available with short lead time.
