Freedom of design – RIM with Telene®
When you need medium or big size parts, which have good impact strength, freedom of design and good adhesion for surface treatment, reaction
injection moulding with unique Telene® material is your solution.
Reaction injection moulding (RIM) is used at both the Finnish and Slovakian factories. Typical applications are agricultural, automotive and construction vehicles and equipment. Maximum part dimensions are 3300mm x 2300mm
x 1200 mm and maximum mould weight is 16 tons.
MSK Plast’s expertise in sustainable RIM
From environmental aspect material has very low CO² footprint trough whole process chain from material manufacturing to final part. Our fully customized plastic components are always designed together with the customer.
Manufacturing plastic products by reaction injection moulding guarantees a durable and high-quality outcome. Reaction injection moulding (RIM) is one the most demanding plastic manufacturing technologies. The technology requires strong competencies in manufacturing, plastic extrusion, the processing of liquid material and the further processing of finished plastic products, such as painting and assembly.
Reaction injection moulded plastic products are
extremely durable
This manufacturing technology is most suitable for medium-sized and large plastic items with maximum dimensions of approximately 3.3 m x 2.3 m x 1,2 m. Reaction injection is also used for plastic when the production volume ranges from hundreds to tens of thousands of items per year. Reaction injection moulded components are extruded using aluminium moulds. Thus, small volumes may also be manufactured cost-effectively.
Demanding and large plastic parts for industrial needs are generally manufactured by reaction injection moulding. The automotive industry in particular uses reaction injection in its applications. It is most typically used for vehicles and devices in agriculture and the automotive and excavation industries. Reaction injection moulding is used to manufacture items such as high-quality and durable machine covers, engine and mudguards as well as external cladding parts.
Telene® is a versatile material for reaction injection moulding
Telene material provides excellent adhesion for painting. Products manufactured by reaction injection moulding use DPCD or Telene®. Telene® is a liquid material which does not contain fibre reinforcements, such as glass fibre, but its strength is still excellent compared to other similar materials. Telene® is also highly resistant to high and low temperatures; its operating range is wide, between -40 and +120 degrees Celsius.
The two-component material is mixed right before the material is injected into a mould. The necessary chemical reaction takes place as the liquids are mixed together.
After the injection process, the parting lines of finished plastic products are finished with MSK Plast’s modern robotised finishing cells, which guarantee the high quality of the products. The smoothing and variation cutting of items are also possible where necessary.
Painting
Painting is an essential part of reaction injection moulding. Plastic parts made by reaction injection moulding may be readily varied by painting. At the same time, the durability of the plastic product is improved. We use single, dual and triple-layer painting in plastic products as required.
- Two fully automated painting lines are in use in Finland, and robotic and manual painting is used in Slovakia.
- Currently water based urethane paints in use.
- Excellent visual quality of surface combined with good mechanical protection against external wearing.
Reaction-injected plastic products have excellent impact and heat resistance as well as excellent paint adherence. By means of reaction injection technology, variable wall thicknesses, as well as in moulded inserts can also be made in plastic products.
Environmentally friendly RIM
All materials and waste created in reaction injection moulding are further used by burning to create heat energy, thanks to high kilo caloric value of material. For instance, at MSK Plast, we attempt to follow the principles of sustainable development throughout the production chain of plastic products, in a way that minimises pollution of the environment.
Among other things, the CO2 emissions are extremely low in plastic products manufactured by reaction injection moulding, and throughout the production chain from manufacturing the raw material up to the final product.
