Would you like to develop large plastic products or shaped components and have them injection-moulded? HSV TMP is a specialist in injection moulding of large plastic products and your partner in developing and manufacturing large plastic products, housings, shaped components and other plastic parts.
Injection moulding of large plastic products
Relying on our experience in hands-on production, our engineers can help you in your process and in product development. HSV TMP is a specialist in injection moulding of large plastic products. Our clients already experience the benefits of our expertise at the beginning of the process. Our knowledge, the required materials and the sophisticated techniques are used to optimal effect by our design team, who will join forces with you to create the most ideal solution for your plastic product.
If you choose HSV, you automatically opt for sustainable injection moulding of your plastic products, shaped components, housings and other plastic parts. HSV-TMP finds the most optimal solution for you, both in terms of minimising material use and optimising matrix investments, assembly and logistical solutions that will save you time and money. In addition, we use sustainable energy, generated from solar collectors, for the production and assembly of your product, and incorporate recycled materials wherever possible.

Passion for injection moulding
We have decades of experience and the production and logistics facilities you need to make your products. Combining our passion for injection moulded plastics with an in-company engineering department and smart technical solutions, we are delighted to use our extensive knowledge and experience to help you realise your product concepts, which we manufacture at our production locations in Ede and in Leeuwarden.
Following the development process, the construction of the mould and approval of the FOT (first out of tool), production of your plastic product can begin. But how does the injection moulding process work? You can read more information about the four main phases below.
First phase: Plasticising
HSV-TMP uses a gravimetric dosing system. A major benefit of this is that the plastic granulate, colour and any foaming agent can be mixed very precisely in the silo. This promotes constant quality in your product, shaped component or housing, because the material mix remains constant. Material enters the screw from the silo, where it is heated to become a homogeneous, liquid mass. By the time the mixture reaches the injection nozzles, it has reached the correct working temperature and is fully liquid.
The machine now closes the mould. All moving parts in the mould that shape the product in accordance with the required specifications shift into the correct positions. The injection nozzles are pressed against the mould.
Second phase: Dosing
Once the plasticising is complete, the dosing takes place. In this phase, the correct quantity of molten plastic is measured in the screw, so that the correct quantity can be injected into the mould via the injection nozzles.
SThird phase: Injecting, filling the mould
During this phase, the dose is injected into the mould via the injection nozzles. The correct pressure and injection rate are set. These depend on the injection technology used, such as high-pressure injection moulding, thermoplastic injection moulding or cascade injection moulding, and factors such as technical specifications, material quantities, shape and size, etc. The injection moulding machine keeps the mould closed and the liquid plastic mixture fills the voids in the mould.
Fourth phase: Cooling and pressure holding process
The cooling process begins as soon as the liquid plastic is injected into the mould. The shrinkage that arises due to the transition from liquid cohesion to the solid phase is compensated by pressure holding and by injecting small quantities of plastic into the mould. The holding time and pressure level depend on factors including the dimensions of the shaped component. Pressure holding also compensates for the difference in volume that arises during the transition from liquid to solid material.
The mould is fitted with piping, which is connected to a mould heating machine. This device continuously pumps liquid through the piping and supplies warm fluid during the start of the cycle and cooling during the cooling and pressure holding process.
Once the product has cooled sufficiently, the mould opens, the product is ejected and the injection nozzles are disconnected. The injection moulding machine prepares a new quantity of material and the injection moulding cycle can begin again.
What does plastic injection moulding cost?
Various factors are used to determine the costs of injection moulding your plastic product. In comparison to other plastic production technologies, the start-up costs are relatively high. However, a tool or mould has a very long service life and injection moulding is in fact much cheaper in relative terms for larger quantities. HSV can even give a shot guarantee of 1 million products. However, this depends on the type of plastic, the material used to build the mould, and the construction of the mould. To give you an example, we even have moulds in production that have lasted for more than 22 years and still meet the predefined quality requirements, dimensions and model.
HSV-TMP only works with mould technicians who can build durable and large-scale moulds and who use high-quality materials. Would you like more information or to request a quotation? Then use the button below: the design team is ready to help you.
Injection moulding involves melting plastic granules and injecting them into a production mould under high pressure. The molten plastic takes on the shape of the mould. After the plastic cools, the product or shaped component can be removed from the mould.
What are the steps in the injection moulding process?
Your product concepts turned to products. Following steps are involved: Concept development, feasibility study, quotation stage and engineering This approach allows you to improve the quality of your products – and can also help you achieve considerable savings.
What does injection moulding cost?
Every injection-moulded plastic product is unique. A cost estimate is based on various factors, such as product specifications, dimensions of the mould, production numbers, type of plastic and the injection moulding technique.
Many customers involve us in product development at an early stage. That enables them to take full advantage of our knowledge and production techniques.
No two projects are the same, but in many cases a development and production process follows a number of standard, recognisable steps. We have therefore provided a number of examples from our day-to-day practice to illustrate our approach.
