The trend of near-shoring in injection molding is gaining traction as companies seek to reduce lead times and transportation costs. Bringing production closer to end markets enhances responsiveness and enables better supply chain management. Parting lines on injection-molded parts are often visible where the two halves of the mold meet and can be minimized through precise mold design. The choice of plastic material affects not only the molding process but also the final properties of the product, such as its strength, flexibility, and thermal resistance. We can help you identify the right solution for stress cracks in your plastic molded parts. Contact our experts today.

How To Tell If A Package Is Injection Molded

Castings are always stronger less prone to stress fracturing. A part machined out of cast material will often give you a resulting stronger part. If machining the part includes sharp corners, this could become a trap into the material selection being completely wrong for the molding process.Size Robotic automation in injection molding can handle post-molding operations such as part removal, trimming, or assembly, increasing overall production throughput. In plastic injection molding, gate design is critical to achieving molded part quality and productivity. Because gates are designed to allow melted plastic resins to move into the mold cavity, it’s imperative that gate material, size and location are optimized for structural, operational and aesthetic considerations.Material Overmolding is a specialized injection molding process where a second material is molded over a substrate, providing added features like grip, cushioning, or sealing.

How Hot Is Lego Injection Molding

PMC is one of very few plastic injection molding companies that actually has in-house Master Molders and specializes in molding with engineered resins. We provide a comprehensive range of plastic molding services including mold design assistance, modeling, prototyping, manufacturing, and testing. Crystallization rates of certain plastics, such as polypropylene and nylon, affect the cooling time and final properties of the molded part. If the operator opens the gate too soon and the product is ejected before the material incurred proper and even cooling time, the operator has shortened the process cycle. An inconsistent process cycle can lead to uncontrolled shrinkage rates, which then causes mold warping. Venting channels are critical for allowing trapped air and gas to escape during molding, reducing the likelihood of defects in the final part. In plastic injection molding, the first thing to occur in the process is filling the mold with a given resin. Improper plastic injection molding fill rate can result in various part defects, both in part strength and aesthetics.
