Follow the following steps to clean acrylic or plastic parts after precision CNC milling;
Use a coolant to cool the newly molded plastic parts.
Dip the spare parts in mineral spirits. This will help seal the edges and prevent them from sticking.
You can also blow the spiral chips away using a compressed air feed attached to a spindle.
Are large quantities suitable for CNC milling plastic?
CNC plastic milling is one of the most preferred spare parts choices for manufacturing due to its ease of use, and as such, large quantities are also suitable for plastic milling.
Whether for direct plastic milling where plastics are cut and machined or injection molding where molten plastics are poured into a mold and extracted, it is possible to machine plastics in large quantities.
Are small batches suitable for CNC milling plastic?
Due to its cost-effective properties for machining and molding, it is also possible to manufacture small batches of plastic spare parts for your use.
It is important to note that once the initial prototype is machined, all other plastic spare parts become easy to manufacture. This is also true for injection molding, where the successful creation of the initial mold makes subsequent molding suitable, even in smaller quantities.
What is the difference between CNC milling plastic and plastic injection molding?
Injection molding works by injecting molten thermoplastics into molds. Once the mold is completed, the mold opens, and the part is ejected. While CNC milling plastics works by cutting layers of the plastic material using a computer numerical control machine (CNC Machine).
The significant difference between these two plastic manufacturing processes is the state at which each plastic material is used to create its designated spare parts. For injection molding, plastics are heated until ‘liquid’ before being used, and for CNC milling, solid, rigid plastics are used because they are easy to cut.
