One of the top strategies for cost-efficiency in manufacturing is to create a usable mold. A quality template should yield many parts or components in the production process. Noble Precision implements a variety of processes to create these template products. Two of the most commonly used techniques are plastic blow molding and injection molding. These practices provide virtually endless solutions for manufacturing companies of various types and sizes.
Putting Injection Molding and Blow Molding Technology to Use
By making use of two highly effective technologies, we can create templates that serve your bottom line. Both of these processes involve different sub-categories. The specific technique used will depend on the kind of end product that a company produces. The primary difference between blow molding and injection molding is that the first is used to produce hollow parts, and the latter is used to create solid components.
These are different kinds of blow molding processes:
- Extrusion: When this is performed continuously, a hollow tube or partially shaped mass (known as a parison) is fed into the mold and then cut off after formation. When carried out intermittently, each new tube or mass is only inserted after the previous one has been shaped and expelled.
- Injection: A core rod is utilized to form a parison in the shape of a cylinder. The product is then extruded from the machine.
- Injection Stretch: To implement this process, both of the above are combined. First, the plastic is pre-formed. Then, it is fed into a machine, reheated, and blown with compressed air into a bottle.
The following are various types of injection molding techniques:
- Thermoplastic Injection: Thermoplastic polymer is employed to create an end product. This material may be transformed into a liquid state, whether it is heated or has already cooled.
- Hot Runner: This requires a manifold, which heats plastic resin that has been melted. This may be done internally or externally.
- Cold Runner: Plastic resin is injected into a mold cavity via a casting feature (called a sprue). This process can be used to decrease waste, but it may increase production time.
- Overmolding: Also known as two-shot molding, this involves covering a substance with an injection mold. Typically, the covering substance (overmold) is a compound with a texture similar to rubber.
- Insert: Multiple components are combined to form a single product. One substance is inserted in the cavity, and then, another substance fills the remainder of the mold to surround the first component. This can lend more strength to the final product, while keeping its weight as low as possible.
