Dr. Bio Polymers are the new eco-friendly resins that are made up of Compostable polymers & starch blends. The Dr.BIO Resin is a film grade resin and can be processed on standard blown film lines or blow moulding lines. The manufactured products using this resin are degradable in normal land fill environment and get disintegrated within 3-6 months after being disposed off in a land-fill.
The polymer resin can be converted to shopping bags, bin liners, mailer envelopes, agricultural films, sheets, blow moulded bottles etc.
To extrude a thermoplastic polymer, granules are fed into a heat-regulated cylinder inside which an endless screw is turning. Due to the combined effect of the kneading action and heat, the granules are turned into a homogenous mix looking like a paste which is then given the desired shape by the die.
Cast film extrusion is a continuous operation of melting one or more polymers through a slot die to form a thin film that will be conveyed to successive rollers with different functions such us cooling, film finishing, etc., and finally wound onto a roll.
Profile extrusion is a process by which various plastic materials are used to develop quality plastic products. These products have a continuous cross-section such as pipe, nets, 3d printers raw material, drinking straws, decorative molding, window trimming and many others. The basic procedure of profile extrusion is that the polymer is melted into a hollow mold cavity, under the influence of high pressure.
Unlike injection moulding where the process makes individual identical components, the extrusion process makes a continuous length of…
Injection moulding is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed (using a helical screw), and injected into a mould cavity, where it cools and hardens to the configuration of the cavity.
