Rotary Hook Metal Injection Molded Parts

Metal injection molding is known as the most popular part molding technology today. Rotary hook metal injection molded parts is a new type of powder metallurgy near net molding technology that extends from the plastic injection molding industry (near net molding technology refers to the part after molding , it can be used as a molding technology for mechanical components with only a small amount of processing or no further processing. Zhongwei Precision Machinery is deeply involved in the production process of rotary hooks, and now there are Hedesheng, Xiumei, Yongyao, and Japanese Zowan rotary hooks. In-depth cooperation, Qinhuangdao Zhongwei Precision Machinery Co., Ltd. is a research and development, production and sales of copper alloy, iron base, stainless steel base, aluminum alloy, nickel alloy, cobalt alloy, tungsten alloy, cemented carbide and powder metallurgy structural parts.

Product Feature

Metal injection molding is known as the most popular part molding technology today. It is a new type of powder metallurgy near net molding technology that extends from the plastic injection molding industry (near net molding technology means that after the parts are formed, only a small amount of processing is required. Or it can be used as a molding technology for mechanical components without processing. This technology has been vigorously promoted in my country and has been widely used in industrial production and science and technology fields). Metal injection molding technology was first introduced by the national 863 program. It can manufacture structural parts with high density, high precision, high strength, and three-dimensional complex shapes. It has low cost, high efficiency, good consistency, good product wear resistance and high temperature resistance. and other advantages, and easy to form mass production. It is reported that the technology has been maturely applied to the production of sewing machine parts, and has been highly recognized and praised by industry insiders.

Taking the production of sewing machine Rotary hook metal injection molded parts as an example, the traditional production method generally uses cold extrusion to produce blanks. Although the cost of blanks is low, it requires more than 200 processing steps, which leads to high labor costs and low efficiency. The rotary hook blank produced by the metal injection molding technology only needs to be turned on each side and a knife is required for processing, and the finished product can be produced in only 10 processes at most, which saves more than 100 processes compared with the traditional process, which greatly shortens the production cycle and saves money. Large workforce. The products produced by metal injection molding technology, because it is a one-time molding, the cutting material is very small, the scrap rate is low, the energy consumption and management costs such as water, electricity and machine depreciation are also reduced accordingly, which greatly saves the production cost. For example, using metal injection molding technology, 20 workers can produce about 300,000 hook blanks a month, while using traditional techniques to produce 300,000 hook blanks a month requires the cooperation of thousands of workers. In short, the use of the new metal injection molding process can reduce labor costs by about 80%, reduce the overall cost by at least 20%, and greatly improve production efficiency.

Post Casting Process

1. Heat treatment: annealing, carbonization, tempering, quenching, normalizing, surface tempering

2. Processing equipment: CNC, WEDM, lathe, milling machine, drilling machine, grinder, etc.;

3. Surface treatment: powder spraying, chrome plating, painting, sandblasting, nickel plating, galvanizing, blackening, polishing, bluing, etc.

Moulds and Inspection Fixtures

1. Mold service life: usually semi-permanent. (except for lost foam)

2. Mold delivery time: 10-25 days, (according to product structure and product size).

3. Tooling and mold maintenance: Zhongwei is responsible for precision parts.

Quality Control

1. Quality control: the defective rate is less than 0.1%.

2. Samples and trial run will be 100% inspected during production and before shipment, sample inspection for mass production according to ISDO standards or customer requirements

3. Testing equipment: flaw detection, spectrum analyzer, golden image analyzer, three-coordinate measuring machine, hardness testing equipment, tensile testing machine.
