PPI Ltd are a UK based provider of engineering services, offering a comprehensive range of bespoke solutions to a wide range of manufacturing industries. Our areas of expertise include Vacon, Allen Bradley and Control Technique variable speed drives.
The aim of PPi is to assist industries to become more efficient in an ever-increasing competitive market place. This includes energy saving projects on plastic injection moulding, extruder blow moulding and injection stretch blow moulding using integrated control through variable speed drives.
We work with Vacon and Allen Bradley variable speed drives, both known for their reliability throughout the world stage. Vacon is a global, full service provider of VSD's, unlike almost all its competitors, Vacon focuses entirely on variable speed AC drives.
Allen Bradley is part of the Rockwell Automation, a major American firm specialising in servo motors, motion control and factory automation equipment - including the variable speed drives which Proplas specialise in.
PPi directors Stephen Anderson and Bryan Green have many years of experience in the specification and design of industrial solutions from concept to completion, with a history of successful project implementation. This knowledge was gained in high volume production environments, mainly in the rubber/plastics/paper industries.
Proplas are today the recognized experts in saving energy on plastic injection machines of all types.
Our close working relationships with drive manufacturers have enabled us to purchase drives at discounted rates. We pass on these excellent prices to our customers, whether it's a simple drive sale or a full turnkey project.

ENERGY SAVING PROJECTS IN THE PLASTIC INDUSTRY
Proplas are specialists in ENERGY SAVING PROJECTS on plastic injection / blow moulding machines.
We have implemented many successful projects on the following machines; Negri Bossi, Demag, AOKI, Nissei, Magic's, B&W, Bekum's and Sandretto's using the latest energy saving injection moulding techniques.
Proplas have obtained savings of between 20-50%, with a payback of 8 to 15 months.
Examples:
-
B&W double head extruder/blow m/c - Producing 2L HDPE bottles, cycle time = 14secs. Power usage before modification = 28kW, after modification = 14kW. This produced a real saving of �6,497 pa, with a payback of less than a year.
-
Nissei ASB 250 ISB m/c - Producing 2.5L PET containers, cycle time = 24secs. Power usage before modification = 30kW, after modification = 19kW. This produced a real saving of �5,105 pa, with a payback of a year.
-
Demag injection moulding m/c - Producing containers, cycle time = 31secs. Power usage before modification = 41kW, after modification = 26kW. This produced a real saving of �6,960 pa, with a payback of 1.2 years.

Proplas would need to survey your machines to determine what savings are obtainable, various factors influence the possble savings ie.. the running time of the machine, shot size, cycle time, size of hydraulic motor etc...
Proplas can install a test unit onto your machine to demonstrate the real savings that you can achieve
