Insert Molding vs Overmolding
Overmolding molds one part from one material and then molds another material over the first molded part. That’s why it’s sometimes called multi-material molding or, when injection molding is used, two-shot molding.
Insert molding begins when a pre-fabricated, pre-formed, or previously molded part is placed in a mold and then molded over with a different material. Sometimes, the insert is made of metal. However, non-metal inserts can also be used.
With overmolding and insert molding, parts are bonded together seamlessly. Whether it’s to improve comfort, provide sealing, increase safety, or reduce noise and vibration, these two processes are used in a range of applications
FAQ
Q:What are 4 stages of injection molding?
A:Injection molding is a precise process with four key stages for producing high-quality plastic parts:
Clamping: The mold’s two halves are securely clamped together to prevent opening during injection, ensuring the molten plastic stays contained.
Injection: Molten plastic is injected under high pressure into the mold, filling every cavity to form the desired shape.
Cooling: The plastic cools and solidifies within the mold. Controlled cooling ensures the part retains its shape and mechanical properties without defects.
Ejection: Once cooled, the mold opens, and the part is ejected using an automated mechanism, allowing the machine to begin the next cycle.
Q:How much does your injection molding service cost?
A:The pricing for our injection molding services is influenced by several factors, such as the size of the part, mold design complexity, material choice, cavity count, and any additional finishing processes. Since every project is different, we offer customized quotes to give you an accurate cost breakdown based on your specific requirements. Our clear and transparent pricing ensures you know exactly what to expect before moving forward. For an accurate estimate, just submit your project details on our platform, and we’ll evaluate the necessary factors to provide you with a detailed quote
Q:What are the typical tolerances for injection molded parts?
A:In injection molding, achieving accurate tolerances is crucial for ensuring parts fit properly and perform as designed, preventing any potential assembly problems. At Craft, we follow the industry-standard ISO 2768-c for general tolerances, widely accepted for molded components.
