Overmolds is a kind of injection overmolding. Allows an additional layer of resin to be added to an existing molded part to provide a combination of properties not possible with a single material.
Comparing Overmolding Methods
Factors Favorable for Overmolding | Factors Conducive to In-situ Materials Forming |
Large production volumes, typically through 10,000 parts | Moderate production volumes, typically below 10,000 parts |
The certainty of the design and materials you use will be used throughout your production operation | The need for prototyping or testing materials, or the possibility of design changes |
Spend time and money investing in costly secondary investment tooling and process | When making secondary molds, it is necessary to quickly push products and equipment to the market or meet market demand. |
Requires maximum interlayer chemical bonding | Formulate the design of the chemical bond, and through proper material selection, can provide a strong chemical bond |
Hardware plastic, also known as "hardware plastic, plastic injection molding, metal plastic, iron plastic, copper plastic, cover beer injection molding, metal cover beer plastic" has different names, as the name implies, it is the production of metal parts After completion, overmolding is performed.
In principle, the material of metal cladding, the hardware part belongs to metal materials, stainless steel, brass, aluminum alloy, charging terminals, conductive terminals, wires, steel wires, bearings, metal stamping parts, metal turning parts and other metal parts; plastic parts Commonly used materials include PC, ABS, PP, POM, TPE, TPU, PVC, PA66, PA6, PA46, hard rubber, soft rubber, and fiber-added modified plastics, which are widely used in various fields.
The injection molding machine that can inject two colors at one time can meet consumers' requirements for appearance and make users feel more comfortable using the product
According to different product structures, size requirements, and appearance standards, different injection molding processing equipment is selected. Various types of injection molding processing machines have their own advantages and disadvantages; some injection molding processing costs are low, and injection molds are expensive; some production efficiency is superior, but the size The deviation fluctuates greatly; some dimensional properties are stable, but the production efficiency is not high.
Two-color overmolding injection molding: Plastic overmolding, appearance products, waterproof structures, casing panels, and dimensionally stable products are mostly used
Vertical overmolding injection molding: metal overmolding, strict size, and difficult positioning of overmolding are often used
Double-station rotary vertical injection molding machine: the quantity is large, it is inconvenient to place rubber-coated accessories, and it is often used for difficult positioning of rubber-coated products
Horizontal injection molding machine: It can also be used when there is no problem with the positioning of the rubber parts and the operation is not troublesome.
No matter what kind of injection molding machine is used for the plastic overmolding injection mold, it is necessary to choose the injection molding machine according to the difficulty of product function, overmolding operation, and parts positioning. Different injection molding machines have different injection molds. It is best to find experienced and An injection mold factory with samples of the same type will assist in the selection of injection molding machines and the design of overmolding injection molds.
Appearance products, conductive products, power failure terminals, hardware handles, product reinforcement, waterproof products, electrical products, beauty products, maternal and child products, small household appliances, electric fans, new energy vehicles, game consoles, sports equipment, night lights, desk lamps, etc. The field of application is very wide.
Our Factory
Overmolding injection molds need to fully consider the size of overmolding accessories, overmolding injection molding processing, mold accuracy, product positioning, operation pick and place, and the dimensional accuracy is doubled compared with the requirements of ordinary injection molds. Although the precision requirements of the two-color injection mold are also very strict, the overmolding injection mold is more complicated than the two-color injection mold. The two-color injection molding is integrally formed by the same injection molding machine. The product has not been fully cooled, and the size fluctuation of one-shot molding is not obvious;
