Manufacturing of shoe sole molds – China Manufacturer Jinchen Barefoot Shoes Grounding Shoes

Accuracy of 2D/3D Drawings: Confirm details such as the length of the mouth plate, the relationship between the last sole plate and other components, and the coordination of front-back proportions (as mentioned in the 2D QC Quality Inspection Standards, which include 18 inspection points such as meat thickness, color groove width, and bending groove depth).
Accuracy of 3D Modeling: Ensure that the mold mouth and plate lines align with 2D drawings. Check the position of trademarks, uniformity of meat thickness, and avoid missing patterns or structural errors (refer to the 22 detailed rules in the 3D QC Quality Inspection Standards).
Material and Process Matching: Strictly distinguish the meat thickness, shrinkage rate, and thermal nail specifications for different materials (e.g., RB, TPR, EVA) to prevent mold failure due to material characteristics.

ImplementationImplementation of Standardized SOP: Follow a complete process from order receiving to development, CNC machining, fitter mold repair, and mold testing. Assign QC personnel at each stage to monitor process parameters (e.g., precision control of equipment in CNC and fine engraving workshops).
Mold Testing and Feedback: Track test results after mold testing, analyze issues such as shrinkage and deformation, and promptly adjust files and update mass production data (refer to the engineering department’s “tracking mold testing results” process).
Mold Numbering and Management: Ensure reasonable placement of mold numbers, sizes, and hardness testing areas for traceability and maintenance (e.g., requirement 15 in 2D QC).

Dimensional Tolerance Control: Strictly control the dimensions of all mold components (e.g., the fit of the last arc, the warpage of the inner and outer sides) to avoid unqualified shoe sole products due to excessive tolerances.
Surface Treatment and Details: Processes such as texturing, electroplating, and Teflon coating must meet customer requirements to ensure smooth and durable mold surfaces (e.g., the company provides “one-stop Teflon and air hole services”).
Multi-Version Consistency: Ensure consistent design styles for different sizes of the same model, with no omissions in modifications (e.g., the “flavor guarantee” requirement in item 8 of 3D QC).

Full-Process Intelligent Manufacturing: Equipped with CNC machines, fine engraving machines, 3D scanners, 3D printing resin models, and other equipment to support digital upgrades from design to production (e.g., R&D of “metal 3D printing mold technology”).
Multi-Process Integration Capability: Covers the production of all types of shoe molds, including IP (injection), MD (secondary), RB (rubber), TPU, etc., and provides supporting services such as precision casting, pattern repairing, and Teflon treatment (“one-stop services” ensure delivery efficiency).
Patents and Certification Endorsements: Holds more than ten national patents and has passed ISO 9001 (quality), ISO 14001 (environment), ISO 45001 (occupational health and safety) and other system certifications, ensuring process stability.

Professional R&D Team: Dozens of computer-aided design personnel with full-process design capabilities from 2D drawing, 3D modeling to programming, capable of avoiding production risks (e.g., “avoiding production issues for sole factories and shoe factories”).
Refined Quality Management: Assign QC personnel at each link to implement strict 2D/3D inspection standards (e.g., over 20 inspection points) to ensure high-precision delivery (“high-quality and on-time delivery” principle).
Talent Development System: Regular internal skill competitions and professional training, combined with external recruitment of high-skilled management talents, to build a high-quality, high-combat team (“talent-strengthening enterprise” strategy).

Experience in Collaborating with Leading Clients: Long-term cooperation with domestic and foreign first- and second-tier brands such as Xtep, 361°, Guiren Bird, SKECHERS, PUMA, and FILA, with strong capabilities in understanding and customizing to client needs.
