Zinc alloy Die casting parts are to be made in casting technology , the parts are made in this method are close to or equal to final finished requirements in this way , so it has a more advantages for complex items .

 

 

 

 

Application

 

Casting parts are used for various areas and play a important role  in the industry .

 

1. Aircraft and military items

 

2. Electrical equiments

 

3. Petroleum industry

 

4. Checmical industry

 

5.  Traffic and automobile

 

 

 

 

Advantages

 

1.  Precise process

Investment casting is able to reach the final requirements of the items , and just need a second process  for the some high precise items .

 

2. Homogeneous Structure

Casting parts have to be melt down before forming , the inside chemical elements and struture are  homogeneous .

 

3. Harder material

 The casting parts can be quneched after prototype or final type , this will strenghen the hardness

 

4. Quick delivery

Some investment casting parts can be used without the second process , the delivery will be shortened much .

 

5. Different materials

There  are almost all materials can be casted .

 

 

 

 

Application Tips of zinc alloy 

 

Zinc alloy parts can not be worked in the high temperature or low  temperature (below 0 degree ) .

 

 

 

Materials choosed introduction

 

Stainless steel

 

2) 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 .

 

3) 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 .

 

4) Strong Strength . As stainless steel has more "C" element , especially martensite stainless .

 

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

 

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

 

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

 

8) Resistance to abrasion . High hardness ensures parts can resist abrasion during operation .

 

9) Enviromental protection . Picked material and finish treatment are based on ROHS or GB standard .

 

 

Brass

 

1. Good Corrode resisting .

Parts are made of brass , this kind of material is very resistant for corrossion .

 

2. Ideal abrasive resistance .

The material for part is alloy brass , the hardness can get to HBS150 .

 

3. Perfect conductivity .

The Solidus for part temperature is 821 degrees , and conductivity is 6.5γ/% .

 

4. High Tensile strength .

Brass can gets more hardness once added alloy elements , generally , which can be up to 400δ/MPa .

 

5. Remarkable thermal conductivity .

the thermal conductivity of brass is 80 λ/w under normal temeperature .

 

 

Steel

 

1. Wide application

Carbon steel is widely used for various building and project structure , and the bracket of factory , and bridge , car , vessel and steel tower and so on.

 

2.Easy to process

“C” element of the carbon steel is very few , the hardness is not as the stainles steel and this fits for different process methods .

 

3. Convenient for plating

Most carbon steel products have to be plated with various platings like zinc , nickel , brass and oil etc to keep the products without rust and long service performance .

 

4. Best cost

Carbon steel is the best cost in all the steel materails with good quality .

 

5. Enviroment friendly

All chemical elements and surface treatment are meet for the relative standards .eg , GB , ROSH etc

 

6. Perfect stability

Inside components and instructure of part are reformed after quenching , keeping this status long time , and that make part satisfied expect requirements .

 

7. Easy to welding

Alloy element of carbon steel belows 5% this make welding is very easy to be done and get good apperance

 

 

 

 

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 ;

All goods were finished , they must to be tested and checked before package ; In this phase , goods will be checked in full inspection or partial inspection . and checking methods can be by handle or auto-machines .

 

(5) Packing

Packed in polybags and cartons or in small color bags .

 

(6) Last inspection ( spot checking , packages status , quantity etc )

When all goods are ready , we will make a final inspection for quantity and package’s status .

 

(7) Delivery

Everything is ready , we will deliver goods to appointed place or port according talking

 

 

 

Packing

 

1. In bulk

 

 

chipboard cartons with belt on the outside

 

Items are packed in apparent polybags and solid cartons then , usually 3-5 bags in each carton and the gross weight is about 15 kilograms .
