PEEK injection molded parts Applications:

In the fields, the transportation industry such as automobiles (including aviation) accounts for about 50% of the consumption of PEEK resin, semiconductor manufacturing equipment accounts for 20%, general mechanical parts such as compressor valves account for 20%, medical equipment and analytical instruments and other products 10% of the market.

1. Transportation machinery such as automobiles

The growth of PEEK resin in the European market is especially rapid in the auto parts market. In particular, the parts around the engine, transmission parts, steering parts, etc. have chosen PEEK plastics instead of some traditional high-priced metals as manufacturing materials. Demand for PEEK resins will continue to grow as the automotive industry adapts to miniaturization, lightweighting and cost reduction. A European model has 44 parts that use PEEK plastic instead of traditional metal products.

2. The field of IT manufacturing

Semiconductor manufacturing and the electrical and electronic industry are expected to be another growth point for PEEK resin applications. In the semiconductor industry, in order to achieve high functionality and low cost, the size of the silicon wafer is required to be larger and the manufacturing technology is more advanced. special requirements, this will be where PEEK resins come into play.

3. The field of office machinery parts

For the separation claws, special heat-resistant bearings, chains, gears, etc. of copiers, when PEEK resin is used instead of metal as their material, the parts can be lightweight, fatigue-resistant, and can be lubricated without oil.

4. The field of wire coating

PEEK coating has good flame retardancy, and its flame retardant level can reach UL94 V-0 level without any flame retardant. PEEK resin also has the advantages of peel resistance and radiation resistance (109 rad), so it is used in special wires in military and nuclear energy and other related fields.

5. Plates, bars and other fields

In the application process of PEEK in some special fields, the phenomenon of small quantity and large variety is often encountered. At this time, it is very advantageous to use rods, plates and other profiles for machining and manufacturing.

6. Fiber field

PEEK fiber (including monofilament) industrial filter cloth, industrial brushes and other products. In the field of composite materials, the appeal of PEEK fiber lies in its thermoplasticity and high temperature resistance. In addition to heat resistance in industrial filter cloths and industrial brushes, its appeal lies in its chemical resistance and abrasion resistance.

7. The field of medical analysis equipment

Because PEEK can withstand repeated autoclaving, it can be used in medical equipment to manufacture endoscope parts, dental descaling devices, etc. In addition, due to the high strength and low dissolution of PEEK, it has been used in liquid chromatography columns, tubes, accessories, etc. for instrumental analysis. Moreover, because PEEK has good compatibility with the human body, it has successfully replaced the traditional titanium metal as an artificial bone material.The main application areas of PEEK.

PEEK Processing

PEEK material can be processed by injection molding and bar machine form or ideal products. It is not economical for designers to use injection molding when designing PEEK product patterns or small batch PEEK parts. It is usually produced by machining. PEEK material can be processed and finished deburring with the same equipment technology as other engineering plastics. Because PEEK material has good wear resistance and good physical properties, it is generally recommended to use cemented carbide, diamond turning tools and drill bits to operate.

When processing PEEK medical injection parts, it is generally necessary to pre-toughen the peek rod or peek plate, which can remove the stress and residual stress in the parts. Localized temperature increases during machining lead to the production of more stress in the material so that the product can be subjected to a secondary stress relief toughening treatment.

Post Injection Molding Process

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

2. Surface treatment: For some products that require subsequent processing, we can provide surface treatment services to achieve the special purpose of customers. At present, we can provide degreasing, polishing, electroplating (gold, silver, nickel, tin, galvanized, etc.), anodizing, electrophoresis and other surface treatment services for precision parts.

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: automated visual inspection equipment can carry out 100% inspection of products, spectrum analyzer, golden elephant analyzer, three-coordinate measuring machine, hardness testing equipment, tensile testing machine.
