Plastic production

Are you going to start producing a new product or do you want to move production? We offer plastic production of products for a variety of applications, based on first-class expertise. We have the technology and expertise needed to produce plastic products for different sectors. Our technical expertise is high, with employees who have extensive industry experience. Together with our subsidiary Grepi Plast, we handle plastic production of Mezonic's own products, as well as commission production for large and small customers. We develop and manufacture polymer-based technical components for industrial customers with six spraying casting machines, including a 3-component casting machine.

The services we provide include

  • Adaptation of products for mass production
  • Construction of design tools, in cooperation with supplier – usually in Norway, Portugal or China
  • Follow-up during the production of form tools
  • Establishment of quality criteria and production parameters
  • Plastic production, as well as production follow-up at external partners
  • Assembly
  • Packaging

Our expertise in plastic production

For quality assurance of an approved and fully developed plastic product, weight and visual inspection are the main indicators in relation to any quality deviations. We perform an accurate and daily monitoring of these parameters, including using regular microscopy studies of critical areas.

We use most thermoplastics in our plastic production, such as polyethylene (PE), polypropylene (PP), polyamides (PA), thermoplastic rubber (TPE), styrene-based materials such as ASA and ABS, as well as advanced construction patches such as PPS and PPSU. This allows us to bring out products with very different properties from the completely soft materials to high-impact metal replacements, and to vastly different applications ranging from medically certified packaging to to advanced technical components for our industrial customers.

We are experts in these areas in plastic production

Injection molding

Production with complex geometry and high requirements for surface finish.

Shape tools

Form tools are developed when large series are to be produced.

Corrosion in the pipes within the insulation

/ Offshore /
On offshore installations and onshore refineries and other petrochemical plants where there are large amounts of pipe streets, there is a challenge that corrosion may occur in the pipes on the underside of the insulation. There are various methods for detecting CUI problems, among other things. using X-rays and ultrasound, but this is complicated and cost a lot of moneys. The [...]

Hidden corrosion for gas companies

/ Offshore /
How to detect corrosion during insulation? It costs gas companies more than 100 million to detect corrosion, and they have therefore needed to develop a new solution for this.

New requirements for corrosion safety and drainage capacity

SINTEF Byggforsk has new requirements for pipe-in-pipe systems for water supply in homes. The drainage capacity in a manifold cabinet should be at least 0.4 l/s and it should be corrosive. In 2015, Grepi Plast started the development of a manifold cabinet that would be adapted to new requirements in the industry.
