Is injection molding safe?
During the injection molding process, these resins are melted, injected into molds, rapidly cooled and released all within a matter of minutes; all the while emitting hazardous fumes and vapors that pose health risks if inhaled.
Is working in a plastic factory safe?
The common health hazards associated with plastic manufacturing processes include noise, and exposure to respirable airborne particulates, especially polyvinyl chloride (PVC) and styrene, that lead to occupationally induced hearing loss and chronic effects such as decreased pulmonary function and lung disease.
What is mold height?
Mold height in die casting describes the thickness of both mold halves when the die casting mold is closed (mold construction height). The mold height is the distance between the fixed and movable fixing plate resulting from a closed mold (Fig. 1).
What happens when you mix acetal and PVC?
For example, if you accidently mix acetal (POM) with PVC, you and the rest of the people on the shop floor will have an extremely unpleasant emotional and physical experience. Small amounts of either of these two resins catalyzes the decomposition of the other polymer to gases.
What is the importance of mold maintenance?
The Importance of Maintenance To prevent product imperfections and inefficiencies, ensuring your injection mold remains in good condition with preventative maintenance can improve tool longevity and part quality. With interim maintenance the risk of imperfections going unnoticed with a damaged mold is eliminated.
Who is responsible for the safety of injection molding machines?
For those being manufactured, repaired or modified, the responsibility is either shared or split between the user and the supplier. ANSI/PLASTICS B151.1-2017 also lists and details the many hazards present in injection molding machines.
What is melting and conveying in injection molding?
Melting means high temperatures—250 F to 800 F—and conveying means injecting or extruding at high pressures. The minimum pressure in injection molding machines is usually about 16,000 psi, and the maximum can be 30,000 to 50,000 psi. Let’s put that in context.
Is it time to take a break at your molding plant?
In a sense, what happened there can easily happen at your molding plant. Some of our machines work at five times the pressures that caused that oil pipe to blow. It’s time to take a break and review some safety items that apply every day to your job. Safety is not a hot topic in our industry.
What is the global market for injection molding?
The global market for injection molding, the process of injecting molten plastic materials into a mold before solidifying them, was valued at $199.88 billion in 2014, and it’s projected to grow in the near future.
