PRODUCTION PROCESSION

Raw Material Selection and Pretreatment

High-quality metal materials such as brass and stainless steel, or engineering plastics such as nylon and POM are carefully selected. After composition and hardness testing, metal raw materials are cut into fixed-length blanks, and surface oxide scales and oil stains are removed; for plastic raw materials, additives are added according to the formula and dried to remove moisture to prevent bubbles during injection molding.

Precision Molding and Processing

Metal fittings adopt processes such as CNC turning and milling to precisely machine key structures like threads and sealing grooves. For complex structures, blanks are first produced by casting/forging and then finished; plastic fittings are formed by injecting molten raw materials into molds via injection molding machines for cooling and shaping, and some require secondary drilling, tapping or assembly of metal inserts.

Injection Molding

Dried plastic pellets are fed into an injection molding machine, heated and melted, then injected into a mold. After cooling and solidification, the product is demolded. The precision of the mold directly determines the dimensional consistency of the joint.

Surface Enhancement Treatment

Metal fittings are treated with nickel plating, chrome plating or electrolytic passivation to improve corrosion resistance and appearance; plastic fittings can be sprayed and silk-screened to mark specifications, brands and other information, and some need antistatic treatment. The thickness of the plating layer and surface finish are strictly controlled throughout the process.

Automated Assembly and Integration

Oil-resistant and aging-resistant seals, ferrules matching the pipe diameter and other accessories are accurately embedded into corresponding stations through automated equipment. Some fittings require pressing treatment to ensure that the accessories are firm and not loose. Subsequent manual sampling inspection is conducted to ensure assembly quality.

Comprehensive Quality Inspection

Dimensional accuracy is inspected by calipers, thread gauges, etc.; airtightness is tested by connecting the fittings to an air tightness test bench and filling with compressed air at rated pressure . At the same time, strength and appearance defect inspection are completed to ensure each product meets the standards.

Standardized Packaging and Warehousing

Qualified products are individually packaged in plastic bags by specification to avoid scratches during transportation; some products are accompanied by instruction manuals. Finished products are packed and stored in warehouses, which need to be dry and ventilated to prevent metal fittings from rusting due to moisture and plastic fittings from deformation.
