Plastic + Metal Overmolding
Plastic overmolding involves injecting molten plastic material onto a pre-existing metal part to create a composite part with enhanced features, such as improved grip or increased durability. The plastic material is molded onto the metal part by a second injection molding process, using a different mold than the one used for the initial metal part.
Metal overmolding, on the other hand, involves injecting molten metal material onto a pre-existing plastic part. This process can be used to create metal components such as inserts, connectors, or conductors, which are then integrated with plastic parts for improved functionality.
Both plastic and metal overmolding have various benefits, including increased product durability, improved grip and texture, and reduced production costs. These processes are commonly used in the automotive, medical, and consumer goods industries.
Clear Part Molding
Clear part molding is a type of plastic injection molding process used to create transparent or translucent parts. It involves the injection of molten plastic material into a mold that has a polished cavity surface to create a part with a smooth and clear finish. The clarity of the part depends on the type of plastic material used, the mold design, and the molding conditions.
Clear part molding is commonly used in the manufacturing of products such as lenses, light diffusers, display screens, medical devices, packaging, and consumer goods, where the transparency or translucency of the part is required. The clear parts can be made from a variety of plastic materials, including acrylics, polycarbonates, and styrenics, among others.
Clear part molding is a specialized process that requires precision equipment and expertise to achieve the desired level of clarity and optical performance. The process involves careful control of the molding temperature, pressure, and speed to prevent the formation of defects such as bubbles, voids, or sink marks that can affect the optical properties of the part. The mold design and surface finish also play a crucial role in achieving a clear and smooth finish on the final part.
In-Mold Labeling
In-mold labeling (IML) is a process where a pre-printed label or film is placed in the mold cavity before the plastic material is injected. The label is then fused with the plastic during the molding process, resulting in a seamless integration of the label and the plastic product.
This process is commonly used for the production of plastic containers, such as food packaging and bottles, as well as other plastic products that require labeling or decoration. In-mold labeling provides several benefits over traditional labeling methods, including improved durability, increased efficiency, and the ability to produce more complex designs.
The IML process can also help reduce waste by eliminating the need for separate labeling and molding processes, and by allowing for the use of thinner plastic materials, which can reduce material costs and environmental impact.
Metal to Plastic Conversion
Metal to plastic conversion involves replacing metal parts or components with plastic alternatives, which is becoming increasingly popular due to the numerous advantages of plastics over metals. Plastics are lightweight, durable, and cost-effective, making them suitable for a variety of applications in various industries.
This conversion process has applications in the automotive, electronics, aerospace, medical, and consumer goods industries. Metal to plastic conversion helps industries reduce costs, increase efficiency, and improve product performance.

In-Process Welding + Assembly
In-process welding and assembly is a manufacturing process used in plastics production where two or more plastic parts are welded or assembled together during the molding process. This process allows for the creation of complex plastic products with multiple components or parts. During the injection molding process, one or more plastic parts are assembled or welded together while still in the mold, either through heat or ultrasonic vibration. This helps reduce costs by minimizing the cycle time of the finished part. The result is a seamless integration of the various plastic parts, creating a single, unified product.
This process eliminates the need for separate assembly processes and reduces the number of parts required, resulting in cost savings. Additionally, in-process welding and assembly can improve product quality by creating stronger, more durable products with fewer defects.
