Parts are to be made in stamping on a machine and the tolerance is quite small as the good succession and automatic working .

2. High speed

Stamping machines stamp the part at the high speed automaticlly including the material feed in .

3.  Can be process different structures

The most stamping parts are to be designed according to the requirements of the buyers and there is almost no any standard for any one .

4. Steady quality

The parts are formed in a full panel under the pressure , so the inside structures of the material are changed averagely .

5. Bright surface

Stamping parts are formed in one or more one processes under the pressure , the surface is keep the same as before feed in .

Finish options

Different fittings different finishs request , suitable finishs can make screws keep nice surface and anti-rust .

1) Zinc .

this is the most popular treatment , the usual color cover black , silver , yellow and white . more colors see below color card .

2) Nickel .

this is more good finish than zinc and is sole color , many parts are plated also in this finish .

3) Oxidization .

this finish is used for part stainless steel pieces , and the most alumiunm parts .

4) Polish .

the parts will be more bright after polished , especially for stainless steel parts .

5) Paint .

the color of paint is more abundant , it is more paint in different colors . partial paint and full paint for screws .

Material introduction

1. Exceptional Anti-rust performace .

stainless steel material is good resistance from rust ,generally , finished goods can be anti-rusted over 72 hours under 96% salty sprey . so the most goods in outdoor or on seaside are choosed stainless steel as the first material .

As stainless steel contains nickel and chrome elementes , it is one of the best material that on resistance rust , especially for working surroundings with much acidity .

2. Nice surface .

goods are polished after finished forming . this is a good choice for ornamental parts . besides , stainless steel parts also can be finished in different colors per surface of fittings . In fact , stainless part itself has bright appearance .

3. Strong Strength .

As stainless steel has more "C" element , especially martensite stainless .

4. Antibiosis .

Most medical equipments are made from stainless steel as it can be up to 99% on killing bacteria .

5. Outstanding weldability .

The part under normal temperature is showing austenite status , and keep the perfect comprehensive performance .

6. High hardness .

Parts are made from alloy elements material .it is up to HRC58 or more high .

7. Resistance to abrasion .

High hardness ensures parts can resist abrasion during operation .

8. Enviromental protection .

Picked material and finish treatment are based on ROHS or GB standard .

Quality control

(1) Checking material before feed in

all material must be checked according to the requirements of products before put them onto the machines to ensure material is available .

(2) IPQC ( by handle and auto-machined control )

The semi-finished products must be checked in special tools during production , this ensure products are always under control .

(3) Chemical elements analysis and fhysical testing after post treatment

The most metal products need post treatment after finished proudct, all products will be tested after than to make sure the quality of products are meet the related requirement .

(4) The second inspection , sort all finished goods by sorting machines if required ;
