WebPolystyrene (PS) When it comes to injection molding polystyrene, there are two types of plastic that are variants of this resin: high impact (HIPS), and general purpose (GPPS). GPPS is more brittle, and therefore can break more easily. Both are lightweight and inexpensive, and resist water as well as radiation. WebJan 1, 2024 · The HIP process utilizes hot compressed inert gas to apply pressure to the work. In the case of MIM, HIP temperatures are typically 100–200°C less than the sintering temperature and pressures are usually in the range of 15,000–20,000 psi (105–140 MPa).The preferred gas is argon since it has a large atomic size; however, nitrogen can …

WebABS is an easy drop-in replacement for HIPS since the shrinkage is the same and they are both amorphous materials. Next, I addressed the warpage. The bowing or banana shape of this flat shelf could be attributed to mold water problems, molded-in stress, too fast a cycle time, or many other possibilities. I just had to figure out which one it was. WebInstead of burning, thermoplastics like ABS liquefy, which allows them to be easily injection molded and then subsequently recycled. By contrast, thermoset plastics can only be heated once (typically during the injection molding process). The first heating causes thermoset materials to set (similar to a 2-part epoxy), resulting in a chemical ... sharpie poisoning
