OVER INJECTION MOLD
产品分类 : 注塑模具
Over Molding is the process where one material is precision molded over another material, usually rubber (TPE) over plastic, for visual or ergonomic appeal. Very often when the design requires ” soft touch” or waterproofing (IP68), over molding is the manufacturing process that we will use. For over molding success, knowledge of material compatibility is crucial. Our extensive expertise in this field helps assure your end part will have the strong end-application bond and performance that your product success demands. Insert molding can also be combined with over molding using parts made of aluminum, brass, stainless steel, copper, plastic and more.
INSERT INJECTION MOLD
产品分类 : 注塑模具
INSERT MOLDING TECHNOLOGY: When a metal, plastic or ceramic part needs to be embedded in plastic to improve product structure it is called Insert Molding. It is a widely used process and one that YOMURA TECHNOLOGIES specializes in. With Insert Molding, a part is placed in a mold cavity then a selected plastic material is injected directly over it resulting is a single part with the insert(s) encapsulated by the material. This process normally uses engineering plastics for improved wear resistance, tensile strength and weight reduction. Insert Molding can be a highly efficient alternative to the assembly of discrete parts using soldering, connectors, fasteners, or adhesives. It also expands plastic capabilities and can reduce final product cost by limiting the amount of costly metal needed to create a part. And importantly, because we can use conventional single shot injection machines for Insert Molding, tooling costs are lower than with a multi-shot processing. Benefits: Reduced assembly and labor costs Because insert molding joins numerous components with thermoplastic, assembly and labor costs are greatly minimized. For example, a single stamping can be overmolded, then perforated to create multiple circuit paths. Reduced size and weight By eliminating fasteners and connectors, and by combining the physical strength of resin and metal inserts, insert molding yields smaller and lighter components. Increased reliability With every part tightly secured in thermoplastic, an insert molded component prevents part loosening, misalignment, improper terminations, and other problems. The thermoplastic resin also provides improved resistance to shock and vibration. Increased design flexibility Designers appreciate the virtually unlimited configurations that insert molding allows. For example, in creating a 3D circuit board, overmolding permits circuitry to move freely through the part, from inside to outside, up walls, down in holes-and the plastic ties it all together. Materials: Engineering plastic or Thermo Plastic Rubber (TPR) inserted with metal frame die casting, plated copper pin, sockets, wire frames, etc. Applications: TPR + Metal Frame(3C Mechanical Parts) ABS + Al. Die Cast (Sports/ Medical) Eng. Plastic + Patting Pin/Eng. Plastic + Wireframe (Connector) Eng. Plastic + Copper Pin/Contact (Precision Electronic Component)

LIQUID INJECTION MOLDING
产品分类 : 硅胶注塑机
Liquid Injection Molding (LIM) and Transfer Molding are preferred processes for manufacturing solid silicone rubber items used in a wide range of applications such as medical equipment, watersports, gas masks, military gear, waterproof device cases, 3C products and much more. MATERIALS: Shin Etsu / Dow Corning/ GE Silicones ADVANTAGES & APPLICATIONS: Low viscosity and lower injection pressure, good for silicon molding Good chemical stability and environmental protection High dimensional accuracy It produces high quality parts without secondary finishing and allows much shorter production cycles than other processes. Over-molding together with hard plastic frame (PC or ABS etc.) for waterproof devices, shock proofing, shielding, etc. Very thin wall design (0.25mm thick around) for silicone to adhere on plastic housing (rib) to meet the demand of low profile product design. Water proof feature can be secured by the combination of soft rubber contacts and with constant pressure provided by hard plastic housing (rib).
METAL INJECTION
产品分类 : 注塑模具
Metal injection molding (MIM) is a metalworking process by which finely-powdered metal is mixed with a measured amount of binder material to comprise a ‘feedstock’ capable of being handled by plastic processing equipment. This is cost-effective for small, intricate, high-volume products which would otherwise be quite expensive to produce by alternate or classic methods. Mold Interconnect Device (MID) integrates a circuit into a plastic part reducing weight and dimensions. We use an innovative assembly process: from injected mold to laser etching then plating with copper or gold.
