Industrial Apparel Presser Foot Sewing Machine Parts Sewing Accessories

MIM metal products are used for various forms of presser feet, presser foot assemblies, base plates, etc., which are used in sewing machines to withstand the abrasion of sewing threads, needles, and the object being sewn, as well as the stress of processing.

Due to the continuous friction with the surface of the tool, the hardness and abrasion resistance of the tool material is severely tested, and if the thread color is light, there is also the concern that the friction sheds the surface material of the tool, resulting in rust stains and discoloration of the sewing thread.

Many MIM products are used as mechanical parts of sewing equipment.

Design elements of MIM sewing and embroidery machine parts

As a result, there are several strict requirements for sewing and embroidery tool materials:

•  The material texture must be hard and wear-resistant, and is required to be able to have at least HRC 40 degrees;

•  Due to the continuous friction of the sewing thread, the surface of the material must not chip off and cause rusting of the sewing thread, and the integrated design of the parts will contribute to the strength and cleanliness of the tools;

•  Able to conduct heat quickly to dissipate the heat caused by the friction of the sewing thread to avoid possible melting of the sewing thread;

•  Dimensional tolerances of parts and assemblies;

•  Due to the high wear and tear, it must be frequently disassembled and replaced, the price of the parts should be affordable, and the damaged products should be recyclable to reduce the burden on the environment;

•  The manufacturing process of the sewing tool should have a special design of the guiding surface so that the sewing thread can be smoothly discharged.

For sewing and embroidery process, the use of MIM process can simplify the design of parts, and avoid casting voids, welding defects, by heat treatment and tempering to enhance the life of the parts, and the use of injection molding to a large number of manufacturing in order to save costs, in particular, the MIM has a plastic injection of beautiful surfaces can be in line with the parts part of the special features to assist the emergence of the thread of the sewing thread smoothly and other advantages, has been the other processes, including casting, die-casting, sheet metal stamping, and the use of MIM, the MIM process can be used in the manufacture of sewing tools. MIM process in sewing and embroidery machine MIM parts will be solid and irreplaceable, this is a MIM completely replaced by the industrial field.

What's the MIM technology and its advantages and features.

MIM is an advanced metal forming technology that use injection molding machine to manufacturing precision and complex metal parts, which combines the advantage of PM and plastic injection molding.

1. It's suit to do mass production with complicated shapes, create metal parts with complex geometries; MIM technology can accurately produce components features such as internal and external threads, undercuts, teeth (e.g., gear teeth), slots, holes, fins, markings, and engravings.

2. MIM process imposes few restrictions on the part design. It gives freedom to manufacture a variety of shapes, can fabricate multi-component parts as a single piece

3. Wide selection of metal materials for MIM, It can use all kind of metal material(such as stainless steel, carbon steel, copper alloys, nickel alloys, tungsten alloys, cobalt alloys, iron, carbide, ceramic and titanium, etc)

4. Its relative density can achieve more than 98%, MIM parts are produced with high density, resulting in excellent mechanical properties, including strength and hardness. This makes MIM a great solution for components that need to withstand high stress and wear.

5. Its finished products is close to final products, less material wastes and scrap than a machining process, which is important for expensive materials such as refractory materials, titanium alloys, superalloys, and specialty metals. reducing the post-treatment cost, and then save production cost.

6. Compared with tranditional CNC and precision casting process, the structure are more even and preformance is much better, Consistent part quality, Consistent part density & strength

7. Compared with PM(Powder Metallurgy), MIM can produce more complex shape and better preformance metal products.

Production cost comparision between MIM and other processes

Cost Effective Design Flexibility/ Material Variety and Integrity

Powder metallurgy can ensure the accuracy and uniformity of the material composition ratio. Suitable for producing products of the same shape and large quantities, low production cost. 

Machinery Structural Parts Manufacture Compare with other process 

Service:

1, 100% inspection before shipment.

2, Satisfied packing, carton, wooden case, pallet,or according to your requirement.

3, Samples are within 35-40 days after the receipt of the deposit. production will be finished about 25-30days after samples confirma

Production Capacity comparision of MIM and other process

Most difficult metals and compounds, pseudo alloys, porous materials can only be manufactured by powder metallurgy
