Product Overview At Shenzhen Sunmy Hardware Co., Ltd., we bridge the gap between aesthetic luxury and manufacturing efficiency. This Plastic Volume/Control Knob is designed to replace traditional heavy metal components without compromising on visual quality. Featuring a distinct top indicator slit and a side-locking set screw hole, this knob is manufactured using advanced Plastic Injection Molding techniques, followed by specialized surface treatments to achieve a realistic brushed silver effect. It is the perfect solution for manufacturers looking to reduce unit weight and production costs while maintaining a high-end user experience. Process & Manufacturing Insights Our comprehensive injection molding capabilities ensure consistency and precision in every batch: Precision Mold Design We utilize high-grade steel molds to ensure the cylindrical shape, top slit, and side aperture are formed with tight tolerances (0.01-0.05mm), eliminating the need for extensive post-machining. Material Selection We use high-impact engineering plastics such as ABS, Polycarbonate (PC), or Nylon, chosen for their durability and excellent surface adhesion properties. Surface Engineering (The Metal Look) To achieve the specific look shown in the images, the raw plastic parts undergo advanced finishing processes such as Electroplating (Chrome/Nickel) or Vacuum Metallization, followed by a Brushed Texture treatment. This gives the plastic the cool touch and reflective grain of stainless steel or aluminum. Structural Integrity The side hole is reinforced (compatible with brass threaded inserts if required) to ensure the set screw holds tight without stripping the plastic threads.

Product Overview Shenzhen Sunmy Hardware Co., Ltd. specializes in high-precision Custom TPE and ABS Double Color Injection Molding, Overmolding, and Insert Molding. Designed for industries requiring ergonomic and highly durable components, our multi-material molding solutions seamlessly combine the structural rigidity of engineering plastics (like ABS) with the soft, tactile grip of elastomers (like TPE). This process is highly ideal for power tool housings, household appliances, electronic enclosures, and automotive components, providing superior functionality and aesthetic appeal. Process & Manufacturing Insights Our advanced Plastic Injection Molding capabilities allow for complex, multi-shot processes. In double-color molding and overmolding, a rigid plastic substrate is molded first. A softer elastomer is then precisely injected over or around the substrate to form a permanent chemical or mechanical bond. This eliminates the need for secondary assembly steps, ensuring a highly durable, water-resistant, and aesthetically pleasing finish. Supported by comprehensive in-house tooling capabilities, we utilize premium mold bases and advanced engineering design software to guarantee flawless precision and consistency across every production batch.

Product Overview This ergonomic handle demonstrates our advanced capabilities in multi-material injection molding. By combining a rigid substrate with a soft-touch grip, we enhance both the durability and the user experience of the product. This technology is widely used in power tools, consumer electronics, and outdoor equipment. Manufacturing Process Insight Overmolding Technique First, the rigid core (Glass-filled Nylon) is molded to provide structural strength. Then, the part is transferred to a second cavity (or using a 2K machine) where soft TPE (Thermoplastic Elastomer) is injected over it. Chemical Bonding We select materials that chemically bond during the molding process, eliminating the need for adhesives and preventing peeling over time. Complex Tooling The mold is designed with precise shut-offs to ensure the soft material creates crisp, clean lines without flashing onto the hard plastic. Key Features & Benefits Ergonomics The TPE layer provides vibration dampening and a non-slip grip, improving user comfort. Aesthetics Enables dual-color designs that enhance brand identity and shelf appeal. Durability The glass-filled nylon core creates a nearly unbreakable internal skeleton. Cost Efficiency Two-shot molding eliminates manual assembly of rubber grips, reducing labor costs in mass production.
