Development

PAI plastics - imide (PAI) is a new variety developed in 1964 by the Amoco Corporation Research Institute in Naperville, Illinois, USA.

Trial-made insulating paint in 1965, and later developed ultra-high functional engineering plastics. It was launched in 1971 under the trade name TORLON. It was originally produced in Joliet, Illinois. In 1986, Amoco High Performance Products was established. Greenville, South Carolina expansion. The advent of PAI solves the technical problem that polyimide cannot be injection molded in the past. It can be used to mold various precision products with complex shapes by injection process, and the production efficiency is also significantly improved. Moreover, PAI has good heat resistance, tensile, bending, compressive strength, dimensional stability, and wear resistance are superior to other engineering plastics.

Polyamides and imides are usually formed by polycondensation of phenyltricarboxylic anhydride and diisocyanate in DMF solution. PAI (polyamide-imide) is a new class of engineering plastics containing amide groups. Due to the very stable aromatic heterocyclic structure in the polyimide molecule, it exhibits heat resistance and low temperature resistance unmatched by other polymer materials, and has excellent mechanical properties and dimensional stability in high temperature environments. 

Product Feature

The allowable working temperature in air is very high, PAI Injection Molded Parts has the best dimensional stability in the temperature range of 250℃, excellent wear resistance and friction properties, outstanding UV resistance, superior resistance to high-energy radiation, inherently low Flammability. High strength, high insulation, radiation resistance, corrosion resistance, self-lubricating, small thermal expansion coefficient.

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.

Application

PAI Injection Molded Parts are often used in the production of precision parts for high-tech equipment, as well as occasions with extremely high wear resistance, such as non-lubricated bearings, seals, bearing isolation rings and reciprocating compressor parts, electronics and semiconductor industries. Products used for high temperature, high vacuum, strong radiation, ultra-low temperature conditions, moldings used as aircraft parts, reciprocating compressor impellers, bearing isolation rings, jet engine fuel supply system parts; chip sets and sockets, cup body welding supports ; Used to make precision parts, such as electronics and semiconductor industries, oil drilling equipment, etc.
