Engineering resins accounted for approximately 18% of total consumption last year. Demand for engineering resins is predicted to increase significantly, particularly in the medical market where there is a growing need for higher performing materials in applications like surgical instruments, diagnostic testing, drug-delivery systems more. The evolution of injection molding technology includes innovations in mold materials. Advanced steel alloys and coatings enhance mold durability, leading to longer lifespans and improved production efficiency while reducing maintenance costs. The use of fillers, such as glass fibers or mineral reinforcements, in plastics can enhance the strength, stiffness, and thermal properties of injection-molded parts. The size, complexity, and design of a part significantly impact injection molding costs. Larger parts require more material and longer cycle times, increasing expenses. Complex designs with intricate features or tight tolerances demand more sophisticated molds and extended production times. This can further raise costs.

PMC, founded in 1975, works on a range of molded plastics projects for its customers, including:Plastic Injection MoldingMold Design AssistanceOvermoldingInsert MoldingIn-Mold DecorationPrecision MachiningPlastic WeldingThermal FusionPost-Molding DecorationAssembliesPackaging Precision tooling is key in producing high-quality parts, with tolerances often needing to be within microns for complex or critical applications. The injection molding industry is heavily influenced by global trends. Economic fluctuations, material costs, and technological advancements shape manufacturing strategies. Staying updated with industry developments is crucial for maintaining competitive advantage. The integration of machine learning in injection molding processes enhances predictive maintenance capabilities. By analyzing historical data, manufacturers can anticipate equipment failures and schedule maintenance, minimizing downtime and improving efficiency.
Why Is Injection Molding Used
Tight tolerance parts in injection molding require careful control of variables like temperature, pressure, and cycle time, as well as high-quality mold design, to ensure that the final dimensions consistently meet precise specifications. These plastic injection molders use what are called commodity resins, such as polyethylene and polypropylene. These are common resins that are not engineered for extreme conditions. Living hinges, commonly used in injection-molded parts like containers, rely on the flexibility of the plastic, allowing parts to bend and flex without breaking. These features require specific materials and mold designs to ensure durability. PMC is one of the few plastic injection molding companies who has in-house Master Molders (there are less than 1,000 Master Molders in the entire world). Micro-injection molding is a specialized process used to produce very small parts with high precision, often for medical devices, electronics, or micro-mechanical components. This process requires specialized machines and molds capable of handling minute volumes of material.
