A wide range of thermoplastic and thermosetting polymers are used in plastic injection molding. Thermoplastics, like polyethylene (PE), polypropylene (PP), and polystyrene (PS), are popular due to their versatility and recyclability. They can be melted and molded repeatedly without altering their fundamental properties. Thermosetting plastics, such as epoxy and phenolic resins, harden permanently after being heated, making them suitable for high-heat applications. The choice of material depends on the intended use of the final product, cost considerations, and specific property requirements like strength, flexibility, or heat resistance.

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.

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.

As these innovations and trends continue to unfold, they will shape the future landscape of plastic injection molding, driving efficiency, sustainability, and innovation in this crucial sector of manufacturing.

Prototyping is a critical step in refining designs for injection molding. It allows for the testing and validation of design concepts before investing in expensive mold tooling. 3D printing, in particular, has revolutionized prototyping.

The production and disposal of plastic products have significant environmental implications. Plastic waste, particularly from single-use products, contributes to pollution and poses a threat to marine life and ecosystems. The production process itself can be resource-intensive, often involving the consumption of fossil fuels and the emission of greenhouse gases. These environmental concerns have brought a renewed focus on sustainability within the plastic injection molding industry.

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.

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.

Initial Costs and Tooling: The initial cost of creating a mold for injection molding can be quite high. This includes the cost of design, material for the mold, and the machining process. Therefore, it’s more economical for large production runs where the initial investment can be spread over a larger number of parts.

In summary, plastic injection molding is a pivotal process in modern manufacturing, distinguished by its efficiency, versatility, and high-volume production capability. It involves injecting molten plastic into a mold to create diverse parts used in various industries. The process demands thoughtful design and prototyping to ensure the quality and functionality of the final product.

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.
