Molding Plastic (e.g. purgings, sprues, runners )

Molding or moulding is a manufacturing process that forms liquid or pliable raw material into usable shaped parts. There are various types of molding, such as blow molding, compression molding, extrusion molding, injection molding etc. Plastic is one major raw material that is used through molding machines to form into many products like bottles, buckets, pens, caps, automotive dashboards, toys, chairs, tables, storage containers, tooth brushes and many other plastic products available today. From injection and blow molding as well as extrusion process, a large quantity of waste plastic material is generated through molding machines, such as sprues, runners, excess parison material and reject parts. These waste plastic ranges from small pieces to large blocks (also called "Purgings"), and quality of these plastic waste is almost as good as new plastic raw material, thus properly recycling these plastic waste greatly saves resources. Molding plastic recycling machines like molding plastic shredder can help to make whole recycling much easier.

Molding plastic shredder in molding plastic recycling

These waste molding plastic usually is in very solid and hard pieces, so shredding or crushing is the initial recycling process of these molding plastic scraps. For large molding plastic scraps (purgings), it is usually shredded by a single-rotor/shaft shredder – actually the purgings are shaved into plastic flakes by the high-speed cutting rotor of the single shaft shredder. For small molding scraps, it can be directly granulated by small sized min granulator. After shredding or granulating, these scrap molding plastic is then turned into regrind. Regrind is usually mixed with virgin compound at a predetermined percentage for remolding. Using regrind is a great way to reduce cost, optimize material usage, and reduce demand on natural resources. PROSINO molding plastic shredder and granulator have various designs and sizes available.

PROSINO PS-C-M Series Small Sized Plastic Granulator is also popular as plastic grinder. It features with compact design and small footprint. This is a popular granulating machine mainly used in small-scaled recycling facilities. It is also adopted by some manufacturing plants as a solution of internal waste management. Those small-sized plastic granulator machines are specialized in granulating/crushing small size plastic (soft plastic & hard plastic) and rubber material, including PET bottles, HDPE sanitary containers, nylon, molding sprues, molding runners,[..]

Prosino PS-C series granulator is also referred to as crusher and grinder. It is a high-speed size reduction machine. And it is ideal for granulating materials like plastic bottles/containers, film, plastic pipes, nylon waste, rubber waste, molding plastic (sprues, runners, purgings), cardboard, paper, wood, etc. Being most widely used in plastic and rubber recycling line, these granulators can efficiently cut scrap plastic/rubber items into small and uniform pieces which can then be processed in recycling line or reused for a different purpose. This series of granulating[..]

Prosino PSC-S series Shredding & Granulating Integrated Unit is an integrated machine that combines shredding and granulating/crushing in one comprehensive unit. This equipment is advantaged with its bi-ability. The in-built single-shaft shredding device firstly does the rough shredding and the in-built granulating/crushing device right after crush the relatively big shreds into small granules. Instead of the traditional way of using a shredding machine and a separate granulating machine to the same above job, this integrated unit not only saves financially in terms of[..]

Prosino Single-motor Single Shaft Shredder (PS-S series)  is also popular as single-motor single rotor shredder or one-motor one shaft shredder. It is a multi-purpose shredding machine which can be available for shredding a wide range of material including plastic, rubber, wood, paper and animal bone etc. Designed with a high-speed rotary cutter along with a hydraulic-driven movable press-plate of cutter, this industrial shredder makes the shredding job done in a super efficient and effective way. The rotary cutter is reversible and controlled by PLC system, which well[..]

Prosino Dual-motor Single Shaft Shredder (PS-S series) is aslo popular as two-motor single rotor shredder or dual-motor one shaft shredder. It is a multi-purpose shredding machine which can be available for shredding a wide range of material including plastic, rubber, wood, paper and animal bone etc. Designed with a high-speed rotary cutter along with a hydraulic-driven movable press-plate of cutter, this industrial shredder makes the shredding job done in a super efficient and effective way. The rotary cutter is reversible and controlled by PLC system, which well protects[..]

PROSINO PS-S-B series Single Rotor Shredders are heavy duty size reduction machines suitable for processing a wide variety of materials including plastic, paper, cardboard, wood, textile, etc. Different from traditional single shaft shredder which is equipped with a horizontal hydraulic pusher, this swing arm type single rotor shredder adopts a hydraulic-driven swing pusher which automatically forces material towards the cutting rotor for achieving the most efficient size reduction performance. A replaceable screen is mounted underneath the cutting rotor for controlling[..]
