INJECTION
Injection molding is an industrial production process in which a plastic material is melted (plasticized) and injected at high pressure into a closed mold, which is opened after the solidification of the product.
Generally the injection takes place at high pressures and at temperatures high enough to allow the flow of the "plasticized" material inside the machinery and the mold.
The principle of operation of injection molding is similar to die casting and derived from it.
Some examples:
Blister - technical trays
Assembled baskets - trees
Assembled baskets - pins
Blade cover
Handle
Handpiece
Protective caps
THERMOFORMING
Thermoforming is a hot plastic molding technique, starting from sheets or films, under pressure or under vacuum.
It is a valid alternative to the injection technique especially if:
- The number of pieces to be produced is low, in this case a manual thermoforming machine is used;
- the number of pieces to be produced is high and delivery times are limited;
- maximum production flexibility is required (lots of different finished pieces);
- the thickness of the part walls must be very thin;
- the dimensional accuracy required is greater than one millimeter;
- areas in the sub-box which cannot be removed
