Make the most of your material
The availability and pricing of thermoplastic materials continue to be a challenge, causing havoc for processors everywhere. Now, more than ever, it makes sense to utilize the material you have fully. So why not regrind sprues, runners and recycle them into the process as a percentage blend with your virgin material or use 100% regrind wherever the applications allow.
It is the fastest, easiest way to process your scrap plastic into reusable material: single shaft shredders, heavy-duty granulators. Besides, the press grinders and pulverizers are integral pieces of size reduction equipment for the plastic recycling industry.
Closed Loop Granulation
Sprues, runners, and even small reject parts can be granulated directly beside the press, blended with virgin material and fed back to the injection molding machine as part of a regulated percentage mix.
Plastic Scrap Grinders
There is a little more to researching, selecting and investing in the ideal piece of size reduction equipment. In addition to the scrap grinder of choice, you should consider the equipment used to feed the scrap plastic to the grinder.
In addition to the investment, you should consider insurance. The insurance you purchase shouldn’t be a written policy but a secondary piece of equipment that will ensure that the scrap plastic fed to your grinder will not include contaminants and cause damage to your grinding equipment.
Instead of an insurance policy, metal detector conveyors are ideal for inspecting plastic scrap for metal contaminants as scrap is conveyed to the grinder. Early detection of metal can prevent severe damage to grinder blades.
Metal detection conveyors can detect all metals – steel, aluminum, copper, brass and stainless steel. Electronic controls have a built-in diagnostics circuit, which monitors all the unit’s metal detector functions. Once the conveyor stops, an audible and/or visual alarm will display in the event of a fault.
Plastic injection molding and blow molding processors don’t always recognize the importance of including metal detection conveyors as a part of their scrap grinding process. Let a metal detector conveyor keep your product under strict surveillance and prevent unnecessary machine downtime and costly maintenance in your plant.
Regrind can save you money, stretch your material resources and support sustainable practices.
