Grepi Plast is a Norwegian plastics manufacturer that develops, designs and manufactures injection moulded plastic products. Grepi Plast was established in 1999 and bought by Mezonic in 2014. They have a strong international customer base, including Schneider Electric, Georg Fischer, Bayer Health Care, Beerenberg Corp and Armaturjonsson AS.
Grepi Plast is located in Skien in Norway. Here they develop and manufacture polymer-based technical components for industrial customers with their six manufacturing machines, including a 3-component casting machine.
They have developed and patented their own fastening plug system, a clamp for insulated pipes and a friction mount for underwater systems. Grepi's clamp for preinsulated corrugated pipes is the only clamp that does this job on the market. It caught the attention of Swiss firm Georg Fischer JRG AG, which later acquired the legal rights and it approved the patent internationally.
For many customers, we are a contributor to product development or product improvement. We have particular expertise in what is required for the products to be produced in large volumes at the right price and quality.
Grepi is a centre of expertise on material technology, and has particular experience in choosing the right material to get the expected properties in a finished product. If we don't have the experience needed, we involve our partner Norner AS, which is a global market leader in industrial R&D on polymers.
A good and stable production of large numbers of units over many years is demanding good form tools. Development of design tools is a separate subject and Grepi has its own tool designer, in addition to working well with TK Nor AS. During this development, there is typical involvement from both the product developers, the tool constructor and those who will produce the products.
We have tools that have produced up to 12 million units in the same tool, but usually design the tools for a slightly more moderate number. The form tools we usually get produced in Norway, Sweden, Portugal or China.
The plastics manufacturer Grepi produces quality technical products in advanced thermoplastic technology for furniture, catering, computer/electronics and pharmaceutical industry, to name a few.
A product often consists of many components. We can therefore also offer the final finish of the products we produce. For quality assurance of an approved and fully developed plastic product, weight and visual inspection are the main indicators to detect any quality deviations. We perform an accurate and daily monitoring of these parameters, and can also conduct regular microscopy studies of critical areas. Together with each customer, we agree on the level and scope of quality assurance.
Besides, we handle: marking, montage, component and system test and packing.
We specialize in injection molding. At the factory in Skien we have eight casting machines where we can produce components from 0.5 grams to 250 grams, in series sizes from a few thousand to many millions. One of the machines is a 3-component machine, so we effectively produce products where several types of materials are included.
Moreover, we have close and well-functioning cooperation with manufacturers in Denmark and Asia, for cases where we do not have suitable machines or capacity, or where we want to use external expertise. At AVK Plast A/S in Denmark, we produce products with unit weight up to 11 kg, for our sister company Mezonic Recycling Solutions AS. To follow up and maintain good cooperation with our Chinese partners, we have our own engineer in China.
