About Plastic Molding
Basics of plastic molding
The method used for the molding of thermoplastic is to melt thermoplastic at the high temperature of approximately 200℃ and pour it into a low temperature mold to solidify.
On the other hand, because thermosetting plastic solidifies at a high temperature, it is heated to somewhere around 50℃ to give it fluidity, then poured into a mold warmed to approximately 150℃ to solidify.
Although materials are classified as plastic, each possesses various features and characteristics.
Below is a list of basic materials, their features and use for your reference.

Plastic Moldings
Accelerator pedals
This is an organ-style pedal used as an acceleration pedal for 4-wheel vehicles with hinge structure. Use of aluminum decoration enables various product designs.
Chair (back, seat)
This is a chair with meshed back and seat. There are two types of products available; one made by installing mesh in the metal frame (melt stick method) and one made by installing mesh on plastic frame without the use of metal frame (mesh insert method).
Air conditioner fan
This is fan part used inside air conditioners. Because it is a hollow structure and molding with mold is difficult (under cut), it is molded by bonding several plastic parts using ultrasonic welder.
Medical equipment parts
This is a part used for ultrasound probes. A plastic very similar to the acoustic impedance of the body surface is applied for product design.
Filtration equipment
This is a thick tube-shaped part used for fine filter units.
It is generally know that thick parts are not suitable for plastic injection molding; however, we are able to control processing parameters, modify the plastic compound and the mold structure, which has enabled us to employ plastic injection molding where the die casting has been used in the past.
