This versatile manufacturing process enables accurate, durable and high-quality plastic components. We manufacture products for demanding applications, and our efficient processes ensure fast delivery and competitive prices.
What is injection molding?
Injection molding, also known as injection compression moulding, is a method of manufacturing plastic products in which plastic raw material is melted, injected under high pressure into a mould and cooled. The end result is a plastic product.
Other common production methods for thermoplastic products include extrusion, rotational moulding, blow moulding and 3D printing. Injection molding differs from the above technologies in terms of product complexity, production speed and dimensional accuracy, but it is still essential to choose the right production method for each product.
Process description
The process typically melts the plastic raw material at a temperature of 200-250 °C using both heat generated by electrical resistance and heat generated by friction. The molten plastic mass is injected at high pressure, up to 1,000-2,000 bar, into the mould by means of a screw that moves inside the cylinder. High pressure and temperature require high precision injection moulds and high quality materials to produce high quality products in quantities of up to millions of pieces.
The cycle time, the time it takes to make one, or in the case of a multi-cavity mould, several plastic products, varies between 6 and 200 seconds, depending on the material used, mould performance and other factors.
We are happy to demonstrate the process in more detail, so please contact us.
Injection molding in Finland?
We are often asked how we can serve global customers from Finland. The recipe is quite simple: price, quality and security of supply.
Most factors of production are the same around the world: energy prices, means of production, raw materials, etc. A significant difference arises in how effectively these are used. Decades of experience in manufacturing our own products and exporting them to international markets have taught us a lesson, and we are happy to share this knowledge with our partners. Often in business, people only look at the price, but we want to offer our partners a truly value-for-money solution.
A skilled and multi-skilled workforce is the most important factor for a quality operation and product. We exceed our customers’ expectations every day: could we do the same for you? Contact us.
