Injection Moulding & Filtration
Posted: 1st April, 2015
FILTRATION & PLASTIC INJECTION MOULDING
Injection moulding is the process of injecting molten plastic at high pressure into a mould to form a given shape. Hydraulic pressure is at the heart of most injection moulding machines, regardless of the make. The hydraulic system provides the force behind pushing the product into the mould and then splitting the mould open again.
Water is also used on many injection moulding machines to provide cooling to the tools. The environment that the hydraulic system works under is often subject to both fine particulate and water ingress.
Injection moulding machines require exceptionally clean hydraulic oil as most are servo controlled. Servo’s are manufactured with extremely fine tollerances and any dirt or water ingress can cause them to stick or jam.
Injection Moulding Company manufacturing toys in Nottingham
A toy manufacturer local to Filtertechnik in Nottingham was experiencing damage to hydraulic components on its injection moulding machines due to contaminated oil. This led to costly replacement of pistons (£700-£800 per piston), valves and ultimately the hydraulic oil. Each injection moulding station requires circa 200 litres of clean and dry oil every 3-4 months costing around £600 per oil change.
Filtertechnik were contacted to see if they could simultaneously reduce machine break downs and also extend the life of the hydraulic oil.
Injection moulding Company Employer:
“The Hippo filtration system has worked faultlessly saving us time and money”
The Hippo filter system cost under £2,500 to install and has saved the company many multiples of this investment in saved down time, no equipment spares costs and no catastrophic failures since its deployment. Hydraulic oil changes have been extended to yearly rather than quarterly and could actually be extended further quite safely such is the faith in the Hippo filter!
On-going element usage is not expensive as each Hippo element has a list price of under £35ea.
