FAQ :

What is the process of plastic machining?

Guide to Plastic Machining

Plastic machining involves the use of lathes, mills, cutting machines, drill presses, grinders, and any other controlled machine to fabricate parts or products. These machines are also used when machining metals; however, plastic is far from metal in terms of machining properties

Is polyimide machinable?

In addition to the production of stock shapes and direct formed parts, polyimide materials are easy to machine. Complex components with tight tolerances can be produced on standard milling machines and lathes.

How do you machine thermoplastic?

CNC Machining of Thermoplastics:

Thermoplastics can be machined with general CNC machining tools made of hard steel. The feed rate and cutting speed are two significant variables affecting machining quality. However, a fine, C-2 grade carbide tool might be needed for turning thermoplastics

What is the solvent for polyimide?

Polyimide resin of solvent-soluble type, which is called "X-resin" in short, was discovered lately. It is soluble in dimethylacetoamid (DMAc), and new extensive applications are expected.

What is the process of polyimide semiconductor?

Polyimides used in the semiconductor industry are typically spin coated onto the wafer, allowing for a flat uniform thickness coating of resin material. The resin is then cured into a smooth structural layer, which can be patterned using a lithographic process in much the same way as any other semiconductor layer.

What is the difference between polyamide and polyimide?

Polyimide vs Polyamide: Polyimides and polyamides are different materials. Polyimides are synthetic resins, while polyamides are synthetic polymers and usually do better in thread forms (like nylon).

Which types of machining processes are good for plastics?

Machining Methods

Turning. Fine, C-2 grade carbide inserts are recommended for turning. ...

Milling. HSS tooling works well for most thermoplastics. ...

Drilling. More heat is generated in drilling than in most other machining processes. ...

What is the difference between polyamide and polyimide?

Why Polyimide PCB Material for Flex Designs?

The primary difference between polyimide and FR4 is flexibility. Also, FR4 can be fabricated with a standard manufacturing process whereas PI needs a higher temperature. The choice of substrate depends on the circuit and application requirements
