Injection molding is a widely used process to make plastic products. Since the type of plastic used may vary in physical and chemical properties, a large range of thermoplastics is utilized in this business. The process can be used to make plastic products for household, and large and small business comprises. Accordingly, a product is 3D Designed for manufacturing.
The following parameters are responsible for increasing the cost of Injection Molding:
Complexity of the logo, fonts, etc., that cannot be molded easily increase the cost of Injection Molding
Extra polishing and finishing of the product can increase costs
Undercuts for a product require extra costly material, raising the molding process's price
In a Multi-core cavity, the value of the injection molding machine goes higher
Even while designing multi-tools for multiple cavities, we can't afford a cheap injection molding machine. Simultaneously, doing some adjustments, like, using different pieces of different plastic material with affordable cost rates and then designing them to process them up, might balance the price list
Keeping even wall thickness on the core of the mold cavity helps cool the material evenly; this results in less material and saves the cost
Every part should be drafted as per DFM rules before designing; this helps the finished product to be ejected smoothly and have a better finish
The geometry of the material may consist of die-locked holes. In such cases, extra material goes for sliding. Thus, during 3D Design itself, the number of die locks should be reduced to reduce costs
The pass-thru core is essential for some features like cut-outs, latches, affected components, lifters, etc. Else, such features might increase the cost of injection molding
For elevated, annular, or lifted feature construction, soft plastic materials should be used rather than hardones like nylon or PVC. It helps in better ejection and saves the cost
