Ming Xiao Metal Parts Manufacturing custom produce cold forging parts(such as bolt,nuts,screw,metal pin,metal stud) according to customer’s drawing or sample, we made nonstandard fasteners by cold heading / cold forging or lathing – handle pins, Dowel Pins, nonstandard hex head bolts,squre head bolt,philips head screws,pan head screws,nonstandard screws, nonstandard pins, nonstandard nuts of square nuts,self lock nut,all kinds of metal studs,etc.
Knurling is a mechanical process of rolling patterns on the handles of metal products or other work surfaces, mainly for non-slip.The method of rolling a workpiece surface out of a straight line or a texture with a knurling knife is called knurling. After the workpiece is knurled, it can add beauty and easy to hold. It is often used for the outer surface processing of parts such as thousand bushings and whip wrenches.
The main kinds of knurling patterns are straight knurling, Diagonal knurling, and diamond knurling.
Generally we use cold forging process to produce rough parts, then machining it again by turning,milling and other machining processes to make the parts with good surface and dimensions.This way can make the production cost reduced and the producing processes more less.it’s a more competitive way to produce high quantity parts.
The technology & capabilities for Turned parts : manual lathe turning,automatic lathe turning, numerical control lathe turning, Drilling, Grinding, Thread rolling, knurling, cutting, cold heading, cold forging,hot die forging, welding, Riveting, milling, components Assembly, etc.
The precision tolerance can reach to +/- 0.02 mm, 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 !
