Injection molding stands as the premier method for cost-effective mass production of plastic components. This technique involves injecting molten plastic into a precisely engineered mold and subsequently ejecting the solidified part. By utilizing the same mold tool across production runs, injection molding guarantees consistent quality and precision in every component. Compared to CNC machining or 3D printing, it offers unparalleled versatility in material selection, color options, cosmetic finishes, polishing, and surface textures.

Our Custom Injection Molding Services
At Rockeypad, we offer advanced custom injection molding services to meet diverse manufacturing needs, ranging from intricate silicone keypads to large-scale components. Our state-of-the-art equipment and industry expertise ensure top-quality production with impressive lead times, as short as 20 days.
Plastic Injection Molding:
Injection molding is a high-pressure technique where thermoplastic materials are injected into precisely designed molds. This process is ideal for producing large volumes of consistent and cost-effective parts, including complex silicone keypads. Our facility handles injection machines from 60 to 1300 tons, accommodating a wide range of part sizes and complexities.
Plastic 2-Shot Molding:
Two-shot molding, also known as dual-material or two-color injection molding, involves injecting two distinct materials into a single mold. This process allows for the creation of integrated parts with varying colors or properties, enhancing the aesthetic and functional aspects of products such as silicone keypads and other components.
Plastic and Metal Insert Molding:
Insert molding integrates metal or other materials into plastic parts, enhancing functionality and durability. This technique is particularly effective for components requiring threaded inserts or additional structural strength, such as mechanical parts, wheels, and pulleys.
Plastic and LSR Over-Molding:
Our plastic and Liquid Silicone Rubber (LSR) over-molding process combines the strengths of both materials to produce high-performance multi-material parts. First, we mold the plastic substrate, followed by applying a layer of LSR, ideal for silicone keypads and other applications requiring soft-touch surfaces or enhanced performance characteristics.
Partner with Rockeypad to leverage our comprehensive custom injection molding services, ensuring superior quality and tailored solutions for your silicone keypads and other manufacturing needs.

Custom Injection Moldings Design Guidelines
| Feature | Tip |
| Undercuts | Incorporating pass-thru coring helps to minimize undercuts, thereby reducing the complexity and cost of the tool's ejection mechanisms. |
| Wall Thickness | Maintaining uniform wall thickness in plastic parts helps prevent wall sink and voids, while thinner walls contribute to shorter cycle times and lower manufacturing costs. |
| Drafts | Ensure parts are designed with a minimum draft angle of 0.3°, or up to 5°, for faces with medium textures. |
| Ribs/Gussets | Ribs should be 40-60% the thickness of outer walls and should still maintain draft. |
| Bosses | To ensure structural integrity, bosses should be designed at 30% of the wall thickness in depth, featuring a 30% edge groove, and attached to side walls or ribs. |
