Custom Steel Pins In China
Ming Xiao Manufacturing Co., Ltd engaged in custom steel pins manufacuring more than 20years, we have old lathe turning machines, automatic turning machines, and High precision CNC turning machines, Turning & Milling Compound Machines.
We can optimize the machining processes to make the cost to be lowest, accurate tolerance dimensions we use CNC turning machine, and low toleracne requested dimensions we use old lathe machine to produce, and small turned parts we use automatic lathe machine to produce.
As a professional customized steel pins supplier from China,we can custom producing all kinds Carbon steel pins, alloy steel pins & Stainless steel pins,Copper & Brass pins.
Types of pins:
There are many types of pins, probably: tapered pins, internally threaded tapered pins, cylindrical pins, internally threaded cylindrical pins, open-end tapered pins, threaded cylindrical pins, elastic cylindrical pins, straight grooved light type, bored pins, threaded taper pins, splits Pin etc.
The type of pin is selected according to its work requirements in use. The diameter of the connecting pin can be determined according to the structural characteristics of the connection and based on experience, and the strength should be checked if necessary. The direct positioning of the positioning pin can be determined according to the structure. The length of the pin in each connecting piece is about 1 to 2 times its diameter. The commonly used material for pins is 35 or 45 steel. The materials of the safety pins are 35, 45, 50, T8A, T10A, etc., and the hardness after heat treatment is 30~36HRC. The pin sleeve material can be 45, 35SiMn, 40Cr, etc., and the hardness after heat treatment is 40~50HRC.
We custom Small Metal Parts for all industries, welcome contact us to develop your projects.
The technics & capabilities for machined parts : manual lathe turning,automatic lathe turning, numerical control lathe turning, Drilling, Grinding, Thread rolling, knurs rolling, cutting, cold heading, hot die forging, welding, Riveting, milling, components Assembly, etc.
The precision telorance can reach to +/- 0.02mm, and the surface roughness can reach N6 standard after milling.
Available Materials for machined parts: Aluminum,copper/ brass,stainless steel,stainless iron,carbon steel, Mild steel,cold roll steel, Plastic Bar,etc.
Finish treating: Anodizing,hard anodizing,electroplating of chrome/zinc/nickel plated, tinning,copperize,Colour spray-painting, blackening, hot-dip galvanizing, tephlon plating, etc.
Lead time for custom samples of metal machined parts is 10days.
Lead time for mass production:generally a order is 30-60days, if machining process is too complicated or quantity is very high,the lead time will longer.
We can provide COC (material certificate), Test Report, ROHS / SGS, plating report or coating reports also available !
