Our Company Offers Custom CNC Machining of Metal and Plastic Parts: Custom Sizes, Custom Coatings and Industry Experience since 2007

Our company, Hunan Jiashan Hardware Technology Co., Ltd. (Jiashan Hardware), is an ISO9001-certified manufacturer specializing in custom CNC machining of metal and plastic parts. Since our establishment in 2007, we have accumulated hands-on experience in precision machining since 2007, serving more than 10,000 customers in 60+ countries with 60-70% of our output exported worldwide. From a single prototype to mass production, we turn your drawings into high-quality finished parts with reliable tolerances, professional surface finishes and on-time delivery.

Our Experience in the CNC Machining Industry since 2007

• Founded in 2007 with nearly 100 skilled employees and annual sales of USD 15-20 million
• ISO9001-certified quality system with 100% inspection before shipment
• Precision capability: general tolerances per ISO 2768-M or ISO 2768-F as required, with tighter tolerances down to +/-0.005 mm and surface roughness Ra 0.8-3.2 available for critical dimensions
• In-house processes: CNC milling, CNC turning/lathe, wire EDM, laser cutting, sheet metal bending, stamping, casting, extrusion and injection molding
• Experienced engineering team supporting DFM feedback, material selection and cost optimization

Custom Sizes - Machined Exactly to Your Drawing

We manufacture parts in any size according to your 2D or 3D drawings (PDF, DWG, DXF, STEP, IGES, STP or sample). Standard general tolerances follow ISO 2768-M (medium class), and ISO 2768-F (fine class) is available when your design requires higher accuracy. Whether it is a micro precision component of a few millimeters or a large structural part, our CNC machines and skilled operators deliver consistent dimensional accuracy, clean threads and tight geometric tolerances for both one-off prototypes and volume production.

Custom Coatings and Surface Finishes

We offer a full range of custom surface treatments to improve appearance, corrosion resistance, wear resistance and conductivity:

• Anodizing: clear, black, gold, red, blue or custom colors for aluminum parts
• Plating: zinc, nickel, chrome, gold and silver plating, plus Dacromet and galvanizing
• Coating: powder coating, painting, Teflon/PTFE coating and clear coating
• Mechanical finishes: polishing, sand blasting, bead blasting, brushing and passivation
• Other treatments: heat treatment, black oxide and laser engraving/marking
