In the early 1980’s a privately owned injection moulding company based in Tamworth, England, started the development of a new plastics processing technology that would, over the next twenty years, revolutionise the way plastic injection moulded parts were designed and manufactured.

The process involved injecting a “controlled” quantity of an inert gas (Nitrogen) under pressure, directly into a plastic melt, to form continuous “hollow” channels throughout the part. The process known as “Controlled Internal Pressure mouldings became the acronym for the company name “CINPRES”

Commercial production of plastic mouldings using the new CINPRES technology started in 1984 and one year later the company CINPRES Limited was formed to commercially develop and license the technology on a global basis.

In 1992 the former Sales Director of CINPRES Limited set up a new company, Gas Injection Limited (GIL) to make the technology more user-friendly from both a technological and commercial viewpoint.

Over the next nine years both companies continued to develop specific areas of the technology with Cinpres concentrating on application development activities in Europe and the USA and GIL specialising in the development and manufacture of a new generation of gas injection equipment specifically geared to the emerging markets in Asia.

In 2001 both companies were brought together in a merger following acquisition of GIL by Cinpres’ parent company BI Group to utilise the “synergy” of both organisations and create the world’s market leading company in Gas Assisted Moulding (GAM) technology.

The new company, led by Managing Director Jon Butler, has brought together a team of plastics professionals with over twenty years experience of the process and with the stated aim of continuously developing both equipment and process technologies to ensure that Cinpres Gas Injection Limited offers its customers the best equipment, service and design engineering support in the industry.

Phased Pressure Controllers based on state of the art electro-magnetically operated pressure regulating valves - to more accurately control gas injection pressure profiles - have been introduced.

The PPC gas controllers are supported by an extensive range of Nitrogen GPS- Gas Preparation Systems - including Nitrogen generation based on the PSA - Pressure Swing Adsorption - method, and more recently the Company has introduced a range of compressors designed for continuous operation under varying environmental conditions, and with an ultra low lubricating oil usage. Customers with just one machine or up to forty machines involved in gas moulding are being supplied with high-pressure nitrogen.

After Sales Service
Cinpres offers customers a continuing before and after sales service, including training in the design of gas mouldings, operation of the equipment and in applying the process correctly. Cinpres aims to ensure that all of their customers have the necessary “hands on” initial training and support to ensure that the technology can be “seamlessly integrated” into a customers’ manufacturing process with the shortest of learning curves.

GAM Ancillaries
Cinpres offers a full range of ancillaries for gas moulding, including in-mould and in-nozzle injectors of gas into the plastic.

Cinpres Distributors and Agents
Cinpres has established a network of Distributors and Agents outside the UK, and has established a leading position in South East Asia, North America and Pacific Rim countries. Distributors employ engineers trained by Cinpres to provide a local technical service. (click for comprehensive list of names and addresses). In Germany, Cinpres’ associate, Stieler Kunststoff Service based in Goslar, offers comprehensive services to the extensive German moulding industry. Stieler has developed viable gas cooling methods which offer substantial benefits for their customers. Cinpres is now adding other versions of GAM and other injection moulding processes - together referred to as 'AIM - Assisted Injection Moulding'.

Cinpres is administered and all equipment manufactured at the company's UK headquarters based at Prosperity Court, Prosperity Way, Middlewich, Cheshire, CW10 0GD, United Kingdom.
