Introduction: The first mold trial is not simply about producing a part. It is used to check mold movement, molding behavior, appearance, dimensions, and assembly. Material, sample quantity, critical checks, and the customer's approval method should be agreed before the trial.
Introduction: For non-standard tooling parts, replacement components, and project-specific items, we review material, geometry, process route, inspection, and quantity against approved drawings. One-off and low-volume work still requires controlled revisions, datums, and acceptance criteria.
Typical needs: Components for new tooling, replacement parts for existing molds, custom brackets and connectors, and other reviewed tooling components.
Introduction: Cores, cavities, and inserts often contain complex profiles, deep features, narrow areas, and critical fitting surfaces. Based on drawing datums, tolerances, material, and finish requirements, we plan CNC, EDM, grinding, and fitting operations with dimensional checks at appropriate stages.
Component types: Cores, cavities, inserts, slide-related parts, ejection-related parts, and other precision tooling components subject to review.
Introduction: Die-casting tooling depends on part geometry, alloy, machine conditions, and secondary operations. We review wall thickness, radii, draft, parting, overflow and venting, ejection, cooling, and machining datums, then agree the acceptance method before manufacturing.
Suitable for: New die-cast component tooling, manufacturability review of an existing design, and custom programs requiring tool machining and assembly support.
Introduction: SHIYUNJIA supports custom plastic part programs from product data review and tooling planning through manufacturing, assembly, and mold trials. Before work begins, we review material, cosmetic requirements, critical dimensions, assembly relationships, estimated volume, and target schedule, then document the decisions required from the customer.
