To create a variety of plastic products, plastic injection molding method is the most famous one. By using the injection molding technique, one can produce products of different shapes and sizes. Thermoplastic resins get softened when heated and become hard and rigid again when cooled. The sufficient heat and pressure casts the plastic granules into various forms.
So what does hopper dryer do in molding process? Hopper is a funnel-shaped container which is used to collect the contents before feeding then into the main machine. The contents move and collect into the fixture due to the natural gravitational force. The dryer is installed at the machine throat to absorb all the moisture from the plastic resins. The raw material should be dried out completely before sending it into the main machine to get the final product.
Specially designed dryer distributes hot air uniformly resulting into more efficient drying that keeps the contamination or re-absorption issues at bay. The models available in the market these days offer speedy heating. A good quality heating pipe avoids the resin from burning. Dryer should have complete stainless steel body from inside to avoid over heating damages. Dryers come with easy digital panel for setting timers and controlling the temperature. The overheat protection system of the dryer should be furnished with a fuse to eliminate the possibility of any accident during any mechanical shut down. Dryers with automatic start-up are also available in market. A great number of hot dryers are offered by reputed enterprises. You can browse the internet to select the best one for your use.
