Custom injection molding: This is how we drive your project forward with our injection-molded plastic parts

Plastic injection-molded parts are used in industry if parts are to be tailored to the customer’s needs, robust and inexpensive at the same time. Here, molten plastic is injected in a controlled manner into a mold, compacted and then cross-linked 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 your custom injection-molded parts precisely to your specifications. As a plastics company, we specialise in the manufacture of molded plastic parts in low- and high-volume production in Germany and further afield. Our core competencies also include the manufacture of injection-molding tools and molds as well as design and assembly.

Injection molding: Advantages of the injection-molding process at a glance

Nowadays, it is impossible to imagine modern industry without the injection-molding process for plastic components. It is with good reason that it is the most commonly used process for automated production of molded parts made of plastic. As an experienced top provider among the plastic injection-molding companies, we support our customers in wide-ranging sectors in Germany with high-quality standard and custom injection-molded parts.

The advantages of injection molding in a nutshell:
  • Precise reproducibility: If a large number of identical molded plastic 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 required: Injection-molded parts made of plastic require little to no rework after removal from the mold. This saves the customer time and costs.
  • High level of high 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 high-precision plastic injection molding is thus an exceedingly cost-saving process.

Injection-molded plastic parts: What are the different types of injection molding?

During the manufacture of injection-molded parts made of plastic, one differentiates as a basic principle between duroplasts, thermoplastics and elastomers. The most important plastic 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 processed and brought into the desired form in the same way, i.e. by means of plastic injection molding.
We at LANGER work with conventional technical thermoplastics as well as with high-performance thermoplastics. We have the most suitable material in stock to suit every customer requirement.

Which types of plastic for injection molding are best suited for your project?

Nowadays, an almost unmanageable variety of plastics are available for use in injection molding. They all possess certain advantages and properties that make them better suited for some applications than for others. It can thus be a challenge to find the best material or the ideal two-component injection-molding material combination for plastic parts.
We have summarized the most common injection-molding plastics to give you an initial overview:


Due to their outstanding strength and toughness, polyamides are often used as construction materials. They possess good chemical resistance to organic solvents, but not as good to acids and oxidising chemicals.


PP parts are not only particularly cheap but also flexible and ductile and possess good wear properties. This type of plastic is resistant to chemicals. It is, for example, used for fans, active joints and medical pipette tubes.
Recommended wall thickness: 0.6 – 3.8 mm

Acrylonitrile butadiene styrene

ABS is an extraordinary robust plastic that is also very resistant to chemicals. In combination with it very low cost, ABS is a very common plastic that is used in many industrial sectors. Typical applications are housings for electrical appliances, hand-help devices and visible parts in general.
Recommended wall thickness: 1.1 – 3.5 mm


PC is known to be very resistant to impacts and robust. Furthermore, this type of plastic is heat-resistant. If required, parts made of PC can be transparent, making it the preferred material in numerous sectors. For example, it is used for medical equipment, as bulletproof glass or for lighting elements.
Recommended wall thickness: 1.0 – 3.8 mm

Thermoplastic elastomers (TPE)

Thermoplastic elastomers are materials in which elastic polymer chains are integrated into thermoplastic material. The manufactured parts thus have rubbery properties.

Aliphatic polyamides

The PPAs form an extensive group, whereby every plastic possesses characteristic properties. PPA is very strong and heat-resistant. In addition, it is relatively resistant to many chemicals. This type of plastic is often used for fragile parts such as gearwheels, bearings, bobbins and screws.
Recommended wall thickness: 2 – 3 mm


Polyethylene is by far the most frequently used (standard) plastic in the world and is primarily used for packaging. It stands out due to its high level of chemical resistance, good electrical insulation properties and good sliding properties.

Polybutylene terephthalate

PBT possesses advantageous electrical properties and is robust and flexible at the same time. This type of plastic is resistant to fluids such as oils, greases and fuels and does not absorb external odours. PBT is well suited for the automotive sector as well as for gearwheels, plain bearings and a wide range of everyday electrical appliances.
Recommended wall thickness: 1.2 – 3 mm


POM, also referred to as acetal, possesses good properties with regard to stiffness, toughness, strength and hardness. A special feature is its good lubricity in conjunction with a high degree of elasticity. Due to these properties, POM is regularly used for pumps, gearwheels and link belts as well as electric switches and buttons.
Recommended wall thickness: 0.8 – 3 mm


PPSU stands out due to its dimensional stability, heat resistance and toughness. This material is resistant to certain chemicals and radiation sterilization. PPSU is used, among others things, for car fuses, medical instruments, aircraft interiors as well as plugs and sockets.
Recommended wall thickness: 0.5 – 4.5 mm

Polymethyl methacrylate

PMMA, also referred to as acrylic glass, is scratch-resistant, possesses a high gloss level and, in general, possesses excellent optical properties. In parts with thinner and thicker areas, PMMA causes a particularly low number of sink marks. This type of plastic is used, among other things, for lenses, signs, fibre optic cables and light tubes.
Recommended wall thickness: 0.5 – 2 mm
