OEM/ODM Casting & Machining
Since 2003, Jinpeng has focused on aluminum casting, aluminum die casting and copper alloy casting, delivering rough castings, CNC machining and value-added finishing for OEM/ODM projects.
About Us
Ningbo Yinzhou Jinpeng Vehicle Parts Co., Ltd. was founded in 2003. The company serves vehicle parts, industrial machinery, electrical and electronic applications with aluminum casting, aluminum die casting, copper alloy casting and machining support.
Projects start with drawing review. We evaluate material, geometry, wall thickness, machining allowance, critical dimensions, annual volume and delivery requirements before recommending the manufacturing route.
Services & Capabilities
OEM buyers care about process fit, capacity range, material compatibility and inspection discipline. Final capability limits can be confirmed after drawings, samples and expected annual volume are reviewed.
Suitable for housings, brackets, vehicle parts and structural components that need repeatable batch production.
A practical option for medium or larger parts, complex cast structures and flexible batch requirements.
Copper casting and machining support for conductive, wear-resistant, corrosion-resistant and sealing-related parts.
CNC machining for critical faces, holes, threads and assembly dimensions, with finishing support based on project needs.
Workflow
Confirm material, dimensions, wall thickness, weight, annual volume and quality requirements.
Evaluate casting route, tooling plan, machining steps, finishing and packaging.
Complete trial parts, dimensional checks, assembly feedback and process adjustment.
Track quality by batch, complete final inspection, packaging and shipment.
Equipment & Quality
We can provide equipment capability notes, inspection records, material confirmation and process documents according to project requirements.
Cold chamber / hot chamber die casting, gravity casting, melting and holding equipment configured by project.
CNC machining centers, turning, drilling, tapping, deburring and assembly support.
Dimensional inspection, incoming material checks, first article approval, patrol inspection and final inspection.
Inspection reports, material confirmation, packaging standards and process records based on customer needs.
Critical holes, sealing faces, assembly surfaces and machining allowance are defined early.
Process attention on porosity, shrinkage, inclusions, deformation and surface defects.
Batch, inspection, packaging and shipment records support customer quality tracking.
