Plastic injection molding
When you talk about engineering plastic injection molding is that we are dealing with a semi-continuous process based on the injection of a polymer in a melted state. This is poured into a closed mould under pressure and cold, through a gate that is only a small hole.
It is used for prototyping, small-scale production of plastic parts and the creation of pilot moulds before moving on to large-scale manufacturing.
This process produces a wide variety of custom prototypes and final parts. To do this, manufacturers use a vastly different amount of thermoplastic resins. Also, aluminum molds are used which allow for less expensive pattern creation and much faster manufacturing cycles.
Respecting and complying with the rules
However, in order to achieve these aspects of acceleration and low cost in the molding process, various guidelines set out in the regulations for plastic injection molding established by the regulatory bodies must be met.
The particularities covered by these regulatory standards are fundamental aspects in terms of
- Tolerance
- Size
- Materials
- Surface finishes
- Tilt angle
- Back Issues
- Wall thickness
- Radios
In addition, by complying with all the requirements for the proper plastic injection process, the following question can be answered satisfactorily, which is how to reduce the costs of the mouldt
1. Remove counter-exits
2. Getting rid of unnecessary forms
3. Using a Nucleus-Cavity Method
4. Reducing finishes and aesthetics
5. Designing self-assembled parts
6. Modify and reuse the moulds
7. Paying attention to the feasibility analysis (DFM)
8. Use a multi-cavity mold or a family mold
9. Take into account the size of the part
Injection molding and the importance of its use
This process is used to manufacture a wide range of commonly used products. When you look closely at your desk or home, you can find a multitude of injection moulded products: from bottle caps, remote control housings, console covers, syringes and most products made from plastic.
