On injection molding machines with a clamping force of 500
to 16,000 kN (50 to 1,600 I) plastic parts are produced with a
shot weight of 0.5 g to 8,000 g. The annual consumption of
granules is over Tooo t. The modern machinery and an
optimal qualification of the very experienced employees
guarantees a production of the highest level.
Compact injection molding
1K- / 2K injection molding
1K injection molding
By injection molding a wide range of plastic parts with a weight of 0.5 to 8,000 g is produced.
The entire range is processed from standard to highperformance plastics, with a total of more than 1ooo t of granules per year.
Of course, plastics with fillers, such as carbon / and glass
fibers, talc, glass beads and special settings, eg. B. for
optimized sliding and Abriebwerte used. As a special feature,
super-soft TPLs with a hardness of 30 Shore A 000 are
processed. Various surfaces complete the appearance of the
injection molded parts. From etching structures or graining to
high-gloss polishing, everything can be implemented with our
2K injection molding
If different properties desired on an injection molding, z. B.
hard and soft, offers the 2-component / or or multicomponent injection molding.
To do this, we use different technologies to find the best
possible solution. Even with small quantities.
Contact us. We are happy to help.
We manufacture in the insert process whereby the function
"insert" is taken over directly by the robot in our 500 to 2K
injection molding machine.
For small series sizes
The thermal foam casting process (TSG) is suitable if very different wall thicknesses are realized in one component. Due to the foaming process, these are easier to implement. The component construction can be significantly simplified. For visible parts, the required surface quality is achieved by subsequent painting.
In Mold Labelling
Finishing of plastic
For the refinement of plastic products, inter alia, the film rear
injection, also called In-Mold Labeling (IML) is suitable.
At Lspisa AG, components with a maximum size of T250 x
450 mm are currently produced as standard with backinjected foil.
In this production technology, the system of foil, material,
tooling and insertion technology has to be carefully
coordinated by the specialists.
Of course, we will gladly assist you with any questions.
By means of injection-compression molding, it is possible to produce flat moldings with reduced residual stresses. In addition to the improved optical properties, the
chemical resistance is further improved.
Classic applications are transparent molded parts for plastic optics, such as surgical lights.
We are happy to advise you on the implementation of an application for injection-compression molding.
Art for technicians
The gas internal pressure (GID) injection molding allows on
the one hand partially thick walls of the component to
produce without sink marks and on the other hand to reduce
the cooling times of thick-walled injection molded parts. In
addition, the tendency for distortion is reduced in complex
The GID procedure is technically demanding. Not all
materials can be used equally well for this. The injection point
of the gas and the partially required closure of the bore by
the gas needle valve are decisive for the result. In short,
Lspisa AG is the right partner for this.
Larly and close cooperation between product development
and tool and process specialists is recommended. We gladly
Thick wall injection
Free of voids
Under certain circumstances, structural components or visible parts with the highest requirements may require an extreme wall thickness that is unusual for conventional injection molding.
A particular challenge of the injection molding process is the void-free component production. This is particularly noticeable in the case of fiber-reinforced high-temperature materials such as PEI and PLLK.
Wall thicknesses up to 50mm with carbon fiber reinforcement for highly stressed components have already been successfully implemented. Of course, void-free. Our experts will be happy to advise you.
