ZCMIM talk about powder metallurgy powder quality control from MIM products

From powder metallurgy products to talk about metal powder quality control mainly can be divided into two aspects, namely, perfecting the evaluation system of the powder and attentively listen to customers needs.

1.        perfecting the evaluation system of the powder

Mixer - > granulation - > feedstock rheological properties - > feedstock torque - > injection molding - >sintering->product  performance - >  microstructure

2.        attentively listen to customers needs

Ø  recommend suitable MIM material

Ø  provide t MIM technology support

Ø   make performance analysis

Ø  offer MIM marketing information support

ZCMIM is not a manufacturer of metal powder, just hope that through above introduction of metal powder quality control to let more people be familiar with metal powder metallurgy technology, achieving a deeper understanding of metal powder metallurgy process.

Characters for powder metallurgy technology（Second）

Following last article about analysis characters for powder metallurgy technology, other characters as following (reference from ZCMIM): 

Powder metallurgy can not melt the materials and mix any impurity in the course of production, and metal components are sintered in vacuum condition. It unable bring any pollution, so it can prepare high-purity materials with powder metallurgy process.

It can ensure correctness and uniformity of material matching for powder metallurgy.

Powder metallurgy is suitable for produce the same components in mass production, especially for machining gears of high cost, it can reduce the production cost greatly.

Metal injection molding gears

  Metal injection molding products have advantage with high density, high precision, and can be mass production. At present, metal injection molding products are applied in industry, automobile and motorcycle industries, the most widely used products is the metalinjection molding gears.

    As part Structural parts, gears is most used parts of all types. The gear Using metal injection molding in the production have higher accuracy and density, and also can be mass production and processing  

    ZCMIM have 8 years experience of metal injection molding technology, is committed to providing the most durable of metal injection molding gear for customers.

The product development processes of MIM

MIM（metal injection molding）technology is more and more widely used in the manufacture of the metal parts, do you know the process of MIM product development? ZCMIM tell you, there are Seven production process of the product development, Customer needs assessment; Mold development plan; Mold processing; Mold test; Sample make; Trial production; Mass production, let's follow ZCMIM to know the specific work content of each process

1.Customer needs assessment

•       Study of the drawings

•       Study of the product requirements

•       Other requirements and information

2. Mold development plan

•       Time for a day

•       Mould design

•       Product defect analysis

•       Risk analysis

•       Mould schedule

•       Customer confirmation

3. Mold processing and manufacturing

•       Time for 15 days

•       Mould manufacturing agreement with outsourcing mould manufacturers

•       Follow up tooling in progress, and quality

4. Mold test

•       Test time for 3 days

•       Check the pattern

•       computer test

•       check injection molded parts, density, weight, appearance.

5. Sample test

•       Injection molding,

•       Check the appearance, density, weight.

•       skim

•       check the degreasing rate

•       sintering

•       pure plastic

•       QC inspection and deliver (sign) sample.

6. Trial production,

•       Try products order production

•       Trial production, according to the sample production process

•       Trial-produce review

•       Pilot run smoothly,

7. Mass production,

•       Turn production evaluation

•       Turn production

How to anti-rust for powder metallurgy part?

Powder metallurgy process includes forging powder metallurgy, pressure sintering powder metallurgy, isostatic pressing powder metallurgy, metal injection molding etc. In process of production, it need to do anti-rust treatment for easily oxidized (rusted) dense material. Dense material MJ316 rust fluid offers good rust proof treatment with no effect on further process.

Ingredients: film-forming substances, antioxidants, etc.

Features: water-based, coating excellent; high temperature resistance; has a certain anti strain capacity for different parts; rust proof and antioxidant for ferrous and non-ferrous metal.

Application area: rust proof treatment for casting iron, iron-based powder metallurgy products, powder sintering dense material, machined parts and others.

Environmental Security: The solution for environmental water-soluble anti-rust solution; not produce volatile toxic substances; In direct contact with the body, please first with plenty of water to clean.

Instructions: Stirring or shaking evenly before using, immersing or spraying on metal surface then airing or drying

Rust proof life: around 18 months -30 months. Diluted with water may be appropriate to use.

The main advantage of MIM performance

Relative to traditional process with mobility, some complicated parts can be easily done by MIM , not only can improve efficiency, but also save costs. Let’s along with zcmim to take a look at the advantages of MIM!

MIM advantages mainly in the following aspects:

1) can be produced parts with very complex beginning ;

2) high density, its property can be compared with forging material;

3) maximize ability to make final shape parts without subsequent machining or only a small amount of machining;

4) high utilization of materials, suitable for mass production;

5) small equipment investment, and can automatically control the whole process, high production efficiency.

Russian Kalashnikov will use MIM technology for firearm components manufacture

According to Russian sources, the arms manufacturer Kalashnikov plan to turn to MIM process for manufacturing gun components. This forms a part of company's modernization program.   

As the EU and US sanctions, after lost its traditional public goods market, the company said it would turn to Asia, Africa and Latin America markets.

Using mixture as a raw material composed of fine metal powder and polymeric binder,  Kalashnikov firearms parts do not need further process. In year 2014-2015, there were more than 40 new parts being launched, of which 15 have pass tests.

   

Kalashnikov CEO Alexey Krivoruchko said: "One of our strategic objectives is through a series aimed at increasing productivity and efficiency systematic work to improve our product competitiveness in global market." Kalashnikov estimated revenue in 2014 was over 90 billion rubles, but in 2013 was slightly more than 2 billion rubles.
