UK plastic medical moulders Sovrin Plastics has moved into micromoulding of medical components. Karen Sall reports


Sovrin Plastics - an injection moulder based in Slough turns over £10 million (€15m) is ready to open a second facility of 20'000 sq ft, which will add to its existing 50'000 sq ft factory. The investment is £2m (€3m)

The reason for this extention is that the business has outgrown its current premises. It also allows the company to separate the technical (trade moulding) parts with the medical parts. The former will be made at the older premises, while the medical parts will now be made at the new building.

Much of the success of the 35 year old company can be attributed to its long history of special ism in injection moulding technically challenging parts rather than high volume run of the mill products.

Today 50% of Sovrin's turnover is generated from technical parts such as housing for central heating thermostatic valves and optical products such as CCTV plastic domes. The other half comes from medical products such as drug delivery devices for pharmaceutical comapnies.

 

"The success of our business is due to innovation and investment in technology. We are constantly looking at ways in which we can improve a product," says Andrew Rankin Sovrin's operational director. "We were the first company in the UK to invest in micromoulding, to make parts that are barely visible to the eye."

Sovrin bought a 5-tonne Battenfeld Microsystem 50 for £100'000 (€150'000) in October 2000. The machine is a bespoke micromoulding manufacturing cell with injection moulding, robotic handling, product documentation, quality assurance and aligned packaging all in class 100 cleanroom conditions.

James Joiner, projects manager at Sovrin, says: "The inspection and handling on the machine is a big part of the process. The checking of each part, measurement and statistic analysis is very important in ensuring the customer get 100% correct parts."

 

Medical Parts being micro-moulded by Sovrin's Battenfeld 50 include keyhole surgery devices and medical implants.

"We are looking mainly at the existing industries that we deal with, where cost isn't the main issue but were they are looking for miniaturise and design for the future," says Joiner. The Machine has some spare capacity at the moment but Rankin firmly believes that the market will grow and that Sovrin will have to invest in a second micromoulding machine by the end of the year.

"Demand is growing as the size of parts gets smaller," he says.

The company is now looking for new application areas. "We are looking at a bio-absorable polylactide polymer for a US product. It is ironic that a customer has to come from the US to the UK for micromoulding technology.

Sovrin is also working with two UK universities - Bradford on polymer technology. Sovrin is working with Cardiff University on a micro machining project. "Cardiff has applied to the Department of Trade and Industry for funding for the project. "We are providing the Battenfeld machine as a resource," says Joiner.

This sort of investment could see Sovrin's micromoulding business grow by 200% in the next two years, predicts Rankin.

Clean Break

Sovrin Plastics was founded in 1968. In 1980 it started injection moulding paediatric nebulisers and in 1985 decided to install cleanrooms. Today it employs 150 people, and 50% of its injection moulding is carried out in cleanrooms. Sovrin has a stable of 52 Demag injection moulding machines ranging from 25 to 240 tonnes. Sovrin also has a toolmaking facility and employs 14 full time toolmakers.

"We offer the complete 'Design and Manufacturing Solution' By having our own toolmaking facilities we are able to react quickly if any changes or modifications are required by our clients," says James Joiner.
