What are the major considerations in the design of plastic parts?
Here are 8 important factors to consider to meet your plastic part design goals for a successful production process.
- Material Considerations.
- Radius.
- Wall Thickness.
- Gate Location.
- Draft.
- Inclusion of Ribs.
- Mold Shrinkage.
- Special Features.
What do I need to know about injection molding?
Injection molding is a manufacturing process in which parts are produced by injecting material in liquid form into a mold. It is most commonly performed with thermoplastic polymers, but can be used with a variety of other materials to include metals and glass.
What is the important part of Mould design?
The first and most important area in mold design is the size of the sprue bushing, runners, and gates. This criterion is critical to ensure that the part can be filled stress-free, packed out, and frozen off to obtain the optimum molded part.
How plastic Moulds are designed?
The sequence of events during the injection molding of a plastic part is called the injection molding cycle. The cycle begins when the mold closes, followed by the injection of the polymer into the mold cavity. Once the cavity is filled, a holding pressure is maintained to compensate for material shrinkage.
What are the basic steps in designing plastic products?
Making you savings at every stage in the process
- 1 – Concept design, re-engineering of designs and prototyping concept design.
- 2 – Material selection, specification and latest polymer technology.
- 3 – Detailed mould flow analysis improved moulding processes.
- 4 – Rapid prototyping in a range of plastics.
What are the guidelines for the design and selection of gates in plastic mold design?
Gate should set on the thickest wall position of molding products, make plastic flow from thick-wall position to thin-wall position to reduce the pressure loss. Melt Plastic should take the shortest possible path(runner), minimal heat and pressure loss, rapid injection to complete the injection process.
What is molding design?
molding, also spelled moulding, in architecture and the decorative arts, a defining, transitional, or terminal element that contours or outlines the edges and surfaces on a projection or cavity, such as a cornice, architrave, capital, arch, base, or jamb.
Why is Mould design important?
Mould design is an important part of the development process when considering the production of a new moulding. Some considerations are given below. The shape of the moulded part has a direct bearing on the time involved in making the mould, the cycle time of the moulding.
