Injection-moulding technology: Tool manufacturer LANGER at a glance
During the design of plastic injection-moulding tools, we draw on 48 years’ experience gained during our company's history. We ensure the consistently high quality of our products using computer tomography, laser scanning as well as optical and tactile measurement. We deliver to customers all around the world and pay heed to a resource-conserving and sustainable way of working during mould construction.
Mould construction: These are the advantages of moulds from LANGER
Injection-moulding tools are permanent moulds that are required to manufacture parts during plastic injection moulding. Plastic injection-moulding tools are generally made out of metal and have a hollow core. If molten plastic is injected, this takes on the exact form and surface finish of the mould. Plastic injection moulds allow a large variety of different parts to be manufactured. Your cost-effectiveness increases with the quantity of parts manufactured, meaning that injection-moulding tools are ideally suited for series production.
Using modern 3- and 5-axis milling centres, we manufacture precise plastic injection moulds by means of CNC machining to meet the customer’s individual requirements. From simple to highly complex moulds, we provide you with custom tools in wide-ranging sizes. Our high-quality injection-moulding tools allow for cost-saving and reliable manufacturing of parts in low- and high-volume series.

Mould construction for plastic parts: Advantages of the injection-moulding process for series production
Today, it is impossible to imagine modern industry without the injection-moulding process. It is with good reason that it is the most commonly used process for automated production of plastic parts. As an experienced manufacturer of injection-moulding tools, we support our customers in wide-ranging sectors with our tool and mould construction services.
The advantages of injection moulding at a glance:
The advantages of injection moulding at a glance:
- Precise reproducibility: If a large number of identical parts are required, injection moulding is the ideal manufacturing process. It guarantees absolute precision no matter how many parts are produced. This makes it an exceedingly reliable method for the manufacture of precise parts.
- Hardly any rework: Injection-moulded parts require little to no rework after removal from the mould. For the customer this results in cost and time savings.
- High level of economic efficiency: It is possible to produce almost any number of copies of a part with a single mould. The greater the quantity, the lower the mould construction costs for each item. Series production using injection moulding technology is thus an exceedingly cost-saving process.
What are the different types of injection moulding?
During the manufacture of plastic injection-moulded parts, one generally differentiates between duroplasts, thermoplastics and elastomers. Here, thermoplastics have the greatest economical significance. Although the different materials differ significantly with regard to their properties, in principle they are all brought into their desired form in the same way by means of injection moulding.
