Over Moulding Services

China Over Moulding Services provided by Honmor refer to a machining process that injects molten plastic (such as TPE, PP, ABS) onto a prefabricated base material (metal, plastic, or rubber) and forms an integrated part after cooling—realizing the combination of different materials’ advantages (e.g., metal’s strength + plastic’s insulation). Honmor focus on providing this product service with superior quality by using advanced dual-color injection molding machines and precision mold technology to ensure precise fitting between plastic and base materials. When clients customize or purchase this service, Honmor is able to adjust material combinations, over moulding thickness and part shapes as per 2D/3D drawings, which fully meet the functional requirements of their end products. These services help reduce assembly steps for customers, as integrated parts made via Honmor’s moulding services need no extra fastening, saving procurement and production costs.

Core Characteristics

Over Moulding Services have three core advantages that make them popular in the machining industry. First, strong material compatibility: Honmor’s product services support diverse combinations (e.g., metal + TPE for anti-slip handles, plastic + rubber for waterproof seals), and the team will recommend optimal material pairs based on customer application scenarios—this flexibility is why many clients choose to purchase the service from Honmor. Besides, its excellent structural integration forms parts in one step which can avoid gaps caused by traditional assembly; Honmor’s precise control ensures the over molding layer thickness deviation is within 0.1mm, which improves part sealing and durability. Third, improved product performance: plastic over molding can add functions like anti-slip, insulation, or corrosion resistance to base materials; when customers order, Honmor can tailor the plastic material to meet specific performance needs (e.g., high-temperature resistance for automotive parts).

Common Application Fields

They are widely used in multiple machining-related industries (excluding aerospace). In the automotive industry, they are used to make wire harness connectors (metal pins + plastic insulation), steering wheel anti-slip grips (plastic base + TPE over molding), and sensor housings (metal brackets + waterproof plastic)—many auto parts suppliers customize products from Honmor to improve part safety and service life. In the electronics industry, they serve to produce USB connectors (metal terminals + plastic shells) and remote control buttons (plastic bodies + soft TPE keys); the integrated structure from Honmor’s service avoids loose parts, so electronic manufacturers often purchase this service for batch production. In the medical industry, they are applied to make syringe plungers (plastic cores + rubber seals) and medical device handles (ABS bases + anti-slip TPE)—Honmor uses medical-grade materials to meet biocompatibility requirements. In the home appliance industry, they are used for blender handles (plastic frames + soft TPE) and hair dryer nozzles (metal cores + heat-resistant plastic), enhancing user comfort and product durability.
