Plastic injection mold is one of the main pillars of the production of industrial plastic parts, and its quality has a direct effect on the speed, accuracy and durability of the final part. In Tehran, one of the most reliable collections that specialize in designing, engineering and manufacturing plastic injection mold is Sun Plastic Factory; A collection that, over years of experience, has been able to improve the standards of mold production at an industrial level.
In this article, we fully examine all the stages and requirements of designing and manufacturing plastic injection mold, the role of raw materials, equipment, engineering software and the benefits of cooperation with Sun Plastic Factory.
Importance of plastic injection mold in industry
Today, more than 70% of plastic products in the market are made through the plastic injection process. The role of plastic injection mold in this process is similar to the blueprint of a building; If the design and construction is not perfect, the whole project will face problems such as resistance, pleats, disproportion of dimensions or reduction of strength.
The importance of these formats can be examined in several ways:
- Guarantee accurate dimensions and reproducibility
- Increase the speed of production of parts
- Reduce the finished cost
- Prevent errors and outliers of the raw material
- Increase the appearance quality and strength of the part
This is why choosing a reliable factory to make plastic injection mold is a critical decision in the production process.
Plastic injection mold design steps
Correct design of plastic injection mold requires engineering knowledge, detailed analysis and use of professional tools. In Sun Plastic Factory this process is done step by step and completely scientific. The main steps are:
1. Part analysis and review of production needs
At this stage, Sun Plastic engineers check the following:
- Part geometry
- Tolerances
- Use type
- Mechanical resistance
- Wall thickness
- Required production volume
These analyzes determine how many holes the mold will have, what type of steel it will be made of, and how the channel system will be designed.
2. 3D modeling
Using specialized software such as CATIA, SolidWorks and Moldflow, Sun Plastic engineers model the exact design of the plastic injection mold. This modeling includes the following:
- Core and floor covering
- Cooling system
- Injection channel and gate
- Location of separation lines
- Ejector system
3. Analysis of melt flow and cooling
In order to avoid warping, incomplete filling and creating pleats, accurate simulation should be done. Using modern tools, Sun Plastic predicts the behavior of the melt in the mold before actual production.
4. Choosing the right steel
The quality of the steel has a direct effect on the lifetime of the plastic injection mold. According to the type of piece, P20, H13, S7 or hardened steels are used.
5. mold making
Building includes the following operations:
- Five-axis CNC machining
- Spark (EDM) and wirecut
- Surface finishing
- Precise mold assembly
- Testing and final modification
Sun Plastic Factory performs all these steps with advanced devices and expert team.
