Our experience has developed considerably over the last 30 years, which is why we rely on the latest injection compression and other technologies in back molding or FIM. Get an overview of our methods and technologies.
INJECTION COMPRESSION
In this process, plastic is injected into a slightly open mold. During or after injection of the plastic, the melt is pressed into the final mold by closing the two mold halves.
| Application: | flat compontens |
| Advantages: | low stresses in the component high dimensional accuracy lower clamping force |
COMPRESSION GATING
With this technology, which has been specially developed for injection-compression molding, it is possible to separate a film segment from the article during the injectioncompression molding process.
| Application: |
transparent and non transparent components with film gate
|
| Advantages: | no visible sprue no mechanical rework |
TURNTABLE MOLDING
Multi-component injection molding using a rotary table on the moving side of an injection molding machine.
| Application: | multicomponent parts |
| Advantages: | 90°; 120°; 180° rotation possible |
SPIN MOLDING
Multi-component injection molding using a swivel platen injection molding machine with two parting lines and two opposing injection units.
| Application: | large-dimensioned 2K / 3K components multi-component injection-compression Clearmelt/ PUR applications |
| Advantages: | Clamping forces that cancel each other out Different processes per “mold half” Smaller mold dimensions |
BACK INJECTION
A decor made of textile, PVC, foil, precious wood, metal or other materials is inserted into a back injection mold and back-injected with plastic.
| Application: | Automotive Interior components with high-quality look and feel |
| Advantages: | Unification of the decor with the supporting component in one process |
IN MOLD CUTTING (IMC)
also known as in-mold trimming, the decoration projecting beyond the component edges is trimmed in the mold during back molding. This is possible both flush with the edge and with an overhang for subsequent edgefolding.
| Application: |
interior pillar covers, seat back covers
|
| Advantages: | Finished component after injection molding Extremely long service life of the trimming mechanism |
FILM INSERT MOLDING (FIM)
In FIM, a preformed or non-preformed, trimmed pre-cut film is inserted into a back-molding mold and back-molded with plastic.
| Application: | Components with function (sensor foils, heating foils) Optical components with printed film |
| Advantages: | Finished components without subsequent painting Function integration (sensor surfaces, heating surfaces) in the plastic part |
DIRECT GATING
Direct molding process for optical components in which a backside gate of the first component is shaded by means of a second component.
| Application: | PC-Glazing |
| Advantages: | Non-visible direct gating No subsequent mechanical processing (sprue separation) No sprue waste |
IN MOLD DECORATION (IMD)
IMD is used to transfer a decorative or protective coating from a transfer film to the component during the injection molding proces.
| Application: |
exterior panels (high glossy or painted), instrument panels, PC-glazing
|
| Advantages: | finished components after injection molding |
GAS INJECTION
In the GIT / GID process, gas injection is used to create cavities in thick-wall areas after the plastic has been injected.
| Application: | Thick-walled components |
| Advantages: |
weight reduction, elimination of sink marks
Shorter cycle time |
THERMOFORMING
This process is used to adapt films to given contours. This is usually done using IR emitters.
| Application: | FIM and IMD components |
| Advantages: | Allows greater stretching of the foils |
