Functional and elegant: What our plastic components offer architects
Plastic injection-molded parts are tailored to the customer’s needs, robust and inexpensive at the same time. To manufacture them, molten plastic is injected in a controlled manner into a mold, compacted and then interlinked and cooled. In this way, both simple and highly complex shapes can be realised in a wide variety of sizes. Short cycle times and low material costs make this process exceedingly economical.
Using state-of-the-art machines, we manufacture custom parts precisely to your specifications. We specialise in the manufacture of molded parts in small batches or high-volume production. Our core competencies also include the manufacture of customer-specific tools and molds as well as design and assembly. From simple injection-molded parts to complex component groups, we find the ideal solution for every order.

Advantages of injection molding at a glance
Nowadays, it is impossible to imagine modern industry without the injection-molding process for plastic parts. It is with good reason that it is the most commonly used process for automated production of molded parts made of plastic. We support our customers with a wide range of high-quality precision components.
The advantages of injection molding at a glance:
The advantages of injection molding at a glance:
- Precise reproducibility: If a large number of identical parts are required, injection molding 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: Parts made of plastic require little to no rework after removal from the mold. 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 mold. The greater the quantity, the lower the costs of each item. Series production using plastic injection molding is thus an exceedingly cost-saving process.
What injection-molding methods are available?
During the manufacture of parts made of plastic, one generally differentiates between duroplasts, thermoplastics and elastomers. The most important injection-molding materials from an economic point of view are thermoplastics. 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 molding.
We at LANGER work with conventional technical thermoplasts, high-performance thermoplastics and thermoplastic elastomers.
We have the most suitable material in stock to suit every customer requirement.

How is a project conducted at LANGER?
As a full-service partner, we are ready to support you during every step of your project. A qualified contact person is available to help you at all times. This is how a project is conducted at LANGER:
Consultancy/pre-engineering
Our specialists contribute their skills to your order right from the start. Qualified staff from different departments work together to find the perfect solution to cater for your needs. In this way, you profit from our wealth of experience and know-how during every phase of your project.
Design and development
We would be happy to take on responsibility for the planning, further development or the complete design of your parts. To this purpose, tell us what your parts are required for and which properties they should have. If you already have a draft design, we would be happy to help with its further optimisation.
Virtual simulation
A key component of our budget-oriented and efficient way of working is the virtual simulation of the parts production. Using state-of-the-art technology, we simulate and thus verify the manufacturing processes in a realistic virtual environment. Besides verifying the feasibility, this also enables optimisation and cost-saving potential to be discovered. The amount of waste is reduced to a minimum and thus also the cost of your plastic components thanks to virtual simulation.
Tool construction
We manufacture finished injection-molding tools in a wide range of shapes and sizes and find the ideal solution for every order. State-of-the-art quality control measures and experienced employees guarantee the consistently high quality of our series-production tools, multi-component tools and prototype tools using computer tomography, laser scanning as well as optical and tactile measurement methods.
Parts production
Our core competency lies in the economical manufacture of precise plastic parts. Your expectations with regard to the finished product are put into practice with perfect dimensional accuracy. The manufacture of our precision parts is automated to a large extent. Material pre-drying is standard at LANGER. We use state-of-the-art technology and equipment to achieve maximum efficiency and cost-effectiveness. The digitalised production planning and the corresponding MES system are a huge advantage here for LANGER.
Quality control
At LANGER nothing is left to chance. After all, the key factors for architectural and construction elements are absolute precision and close tolerances. Our automated quality control process thus ensures that your components precisely meet your expectations. If necessary, we also perform tightness tests. Meticulous measurement equipment management guarantees the reliability of all control processes. The documentation is digitally archived using a CAQ system.
Further processing
Plastic injection-molded parts are often ready for further use directly after cooling and require no rework. However, if the customer would like us to, we are happy to perform further processing steps such as cleaning-up and demolding.
Logistics service
We deliver all around the world and are familiar with the challenges that can arise with international shipments. For this reason, we offer our customers comprehensive storage and logistics solutions including customs clearance and a transport service. In the process, we pay attention to continuous article traceability. We would be happy to enter individual agreements with regard to our customers’ post-series and spare-parts supply.
Reliable and durable: Drainage channels and gratings made of plastic
In the field of architecture and building construction, our customers very frequently enquire about plastic channels and plastic gratings. Which is hardly surprising, as these components require a high degree of stability and can be manufactured economically by means of injection molding.
Drainage channels: Robust channel elements for vehicular traffic applications / slotted channels / drainage channels made of plastic.
Plastic drainage channels ensure rain water flows off in a controlled manner. Plastic drainage channels thus play an important role in the maintenance of land and property, as they hinder the accumulation of water and thus prevent damage. Ideally, drainage channel covers are made of plastic. It is possible to drive over this type of drainage channel cover and they are designed to withstand heavy loads day in, day out. In this context, one refers to heavy-duty channels (channel systems).
Gratings made of plastic/GRP: slip-resistant
Plastic gratings have numerous advantages. They are stable despite their low weight, are permeable to light and air and can be easily installed and removed. Our plastic gratings for vehicular traffic applications are particularly hard-wearing. Even when regularly subjected to heavy loads, they stand our due to their long service life. They are thus the ideal choice for interior and exterior construction work. Upon request, we will additionally reinforce your parts with glass fibre.
