Aug 06, 2017 · PMMA Plastic Injection Molding Process. PMMA, i.e. polymethyl methacrylate, also known as acrylic or organic glass, is a transparent thermoplastic with a relative density of 1.19, which is higher than that of water. With a high surface glossiness, the PMMA products are characterized by strength, rigidity and toughness. The process features of PMMA: due to the high viscosity, PMMA hasPMMA injection molding processing condition
Drying. PMMA is hygroscopic and must be dried prior to molding. Drying at 90 C (194 F) for 2-4 hours is recommended. Melt Temperature . 240 - 280 C (460 - 536 F)

PMMA has water absorption, its water absorption rate is 0.3-0.4%, and injection molding process must be below 0.1% humidity, usually 0.04%. The presence of moisture causes bubbles, gas ray, reduced transparency in the melt, and so on. So we must dry it. The drying temperature is 80-90 and the time is 3 hours or more.

Polycarbonate (PC) has the high impact strength, whereas Polymethylmethacrylate (PMMA) possesses the high tensile strength. Both of them have been widely used for optical elements in illumination. This paper aims to investigate mechanical properties including tensile and impact strengths of PMMA/PC blend with 50 percent of PC concentration by injection molding process.
PMMA Injection Molding Technology of Polymethyl
Injection Molding Technology of Polymethyl Methacrylate (PMMA) PMMA is commonly known as polymethyl methacrylate, acrylic and so on and its chemical name is polymethyl methacrylate. PMMA has some defects such as low surface hardness, easy to snag, low impact resistance, poor molding liquidity performance, so PMMAs modification appears one after another such asPMMA acrylic injection Molding Defect Causes and Solutions
Mar 10, 2020 · 1. Adjust the supply quantity of acrylic pellets. 2. Increase the injection pressure. 3. Increase the injection speed. 4. Raise the barrel temperature. 5. Increase the screw backpressure . 6. Raise the mold temperature for molding of thin-walled products. 7. Extend the pressure holding time during injection. 8. Extend the molding cycle. 9.PMMA injection Molding Process, Acrylic Plastic Injection
Polymethyl methacrylate (PMMA) injection molding is a process where organic glass/acrylic is injected into a cavity to form a particular product upon cooling and hardening. The molds produced by PMMA injection molding are used to make car windows, aquariums, and screens for mobile phones. Acrylic is preferred to glass because it has better abrasion resistance.
PMMA plastic injection molding characters and conditions
Plastic Injection Molding Conditions of PMMA Drying: The drying temperature should be 10-20 (100-110) lower than its heat deformation temperature, while the drying time is about 2-8 hours (drying the water content to 0.02-0.04%). The dried material cannotPlastic Injection Molding Troubleshooting Guide
Injection molding machine 1. The injection pressure within the cavity is too low. Rise injection pressure, check the size of the injection molding parts each time the pressure rises, until the injection molded parts slightly appear. 2. Insufficient plastic inside the cavity. Increase the amount of plastic injection molding or check the bedding.RTP 1800 Acrylic (PMMA) Product Data Sheet - RTP Company
