Video

We are a professional custom sheet metal and CNC machining manufacturer from Beijing, China. We not only have CNC machining and sheet metal machining, but also surface treatment, assembly and transportation.

Whether it is metal parts or plastic parts, simply send us your drawings and we will help you achieve it.

For more than 30 years, we specialize in the field of scientific instrumentation, automotive parts, robotics, semiconductors, and custom machining of automation products. We provide on-demand manufacturing services through CNC machining and sheet metal manufacturing to make your product concept a reality.

We are a professional partner in the field of CNC machining parts, sheet metal parts, metal die-casting and plastic injection parts. For better protection against oxidation and corrosion of parts, the quality, durability and appearance of parts are improved through meticulous surface treatment methods such as polishing, brushing, sand spraying, anode oxidation, electroplating and powder spraying. As your partner, we are committed to providing you with high quality, high precision, high standard customized CNC machining parts.

Spectrometer components Vacuum light chamber
This is the core component of a scientific instrument - a spectrometer, The vacuum photosphere is first formed by moldcasting, the material is made of metal and iron, and it is moulded by CNC milling. Because it is a vacuum chamber, there is a requirement for the vacuum level, which cannot be lower than -9Pa. The casting process requires no air pores, There are no sand eyes, so that the vacuum of parts can be truly ensured, and there are also very high surface treatment processes both inside and outside of the parts. The optical parts use sand spraying technology inside to prevent light refractions, and the parts surface is spray painted, which can prevent oxidation and corrosion of parts, high wear resistance, and relatively aesthetic.

CNC Custom Machining Precision mold manufacturing Parts machining Mold production assembly
This is a injection mold made of high hardness and high wear resistance mold steel, which is custom processed. Mold machining is different from ordinary CNC machining, it requires higher precision, basically within 0.005, and requires the gap between each part, so a mold needs a lot of processes from the selection of materials to the completion of production. These include heat treatment processing of materials, CNC milling processing, wire cutting processing, electric spark processing, welding processing, grinding processing, and key mold assembly, so the mold needs to be repeatedly debugged again and again to finally present a precision mold.
