DFM-Optimized Mold: 4 Success Stories

For over 17 years, GBM Mould has delivered tailored precision mold solutions to automotive, medical, electronic and heavy-duty industries. Below are 4 representative cases where we addressed core pain points (e.g., breakage, long lead times, tight tolerances) with our 5-axis CNC machining, DFM optimization and modular design capabilities.

High-precision 1480 inserts automotive mold for Korean client - 0.01mm tolerance and T1 trial approved.

Korean Auto Client | 1480 Inserts Mold (±0.01mm)

The client’s auto thin-wall parts kept breaking during injection, caused by uneven stress in the mold cavity. We optimized the cavity structure with 5-axis CNC machining and adjusted the gating system to balance pressure.

CNC machining center for medical grade PEEK mold manufacturing

U.S. Medical Client | PEEK Mold (100k Cleanroom)

The client needed FDA-compliant PEEK medical parts but struggled with stability and contamination risks. We used H13 steel and produced in a 100k cleanroom with 5 rounds of CMM inspections.

4-cavity stack mold for electronic connector high volume production

Chinese Electronics | Stack Mold for Connector

The client faced long lead times (30+ days) and high material costs for small connector parts. We designed a 4-cavity stack mold and adopted a parallel machining process to compress the timeline.

5.2 ton large scale automotive mold with 800k shot life

European Client | 5.2 Ton Auto Mold

The 5.2-ton large auto mold required tight ±0.008mm tolerance, but complex alignment issues delayed assembly. We used 5-axis CNC for large cavity machining and a modular assembly design to ensure precision.

FAQs

What is the tolerance accuracy of precision injection molds?

The tolerance of our precision injection molds can be stably controlled within ±0.005mm. Relying on the full-process inspection of 5-axis CNC machining centers and coordinate measuring machines, combined with high-quality mold steels such as S136 and H13, we can meet the customization needs of high-precision industries such as automotive and electronics.

The service life of injection molds is mainly affected by three core factors: first, the material performance of mold steels such as S136 and H13; second, refined processing and assembly technology; third, post-maintenance and usage specifications. We provide customers with professional mold maintenance guidance to extend mold service life.

The development cycle of conventional structure injection molds is 15-30 days, and that of complex multi-cavity and precision insert molds is 30-45 days. Through our standardized production process, we maximize the shortening of delivery cycles on the premise of ensuring quality.

Common reasons for injection mold trial failure include: product size deviation caused by insufficient cavity machining precision; improper matching of injection process parameters (temperature, pressure, injection speed); product deformation caused by unreasonable cooling system design. Our engineers will quickly troubleshoot and optimize parameters to ensure product compliance.

Mold steel selection should be based on product characteristics: P20 steel is cost-effective for ordinary plastic products such as PP and PE; S136 stainless steel is preferred for high-precision or corrosion-resistant products; H13 hot work mold steel is recommended for high-temperature engineering plastics such as PA66. We provide free material selection solutions.

The cooling system is a core component of injection molds. It can precisely control mold temperature, shorten product molding cycles, reduce defects such as plastic part shrinkage and warpage, while reducing mold heat loss and extending mold service life. We customize efficient cooling solutions according to product structure.

Multi-cavity injection molds can inject multiple products at one time, greatly improving production efficiency and reducing unit product cost, which is suitable for mass production of standardized products. We can customize high-efficiency mold solutions with 2-32 cavities to meet different production capacity needs.

We provide 1-year free warranty service and lifelong technical support. If the mold malfunctions, engineers can guide debugging remotely and provide on-site maintenance if necessary. We also conduct regular customer follow-ups and provide professional mold maintenance suggestions.
