KraussMaffei's Multinject technology provides you with the correct system solution consisting of different injection molding variants and mold technologies for your product.
The sandwich technique is suitable for all 2K components consisting of an outer, high-quality skin and an inner component, such as recycled material, plastic foam, or even a filled material.
Process technology:
The cavity is first partially filled with the outer skin material, and the core material is then injected into the core of the outer material. Marbling effects can be achieved by alternately injecting components of different colors.
The separating sliding split technique is suitable for all 2K components in which the preform must be partially released.
Since only one cavity with a core pull function is required, the process can be carried out very easily and cost-effectively.
Process technology:
The injection and cooling of the preform is followed by the retraction of the separating slide. A second cavity is created, which is filled by the second component.
The turntable technology is suitable for all 2K components in which the preform is partially or unilaterally exposed. This technology can be used for unilateral overmolding of large quantities.
Process technology:
After the first component has been injected and cooled, the mold is opened. With the aid of a rotary table on a movable clamping plate, the mold half is rotated in a two-stroke or four-stroke cycle. The preform is then filled with the second component while the first component is simultaneously injected into the free cavity.
The index plate technology is suitable for all 2K components in which the preform must be free on one side at the top and partially free at the bottom.
Process technology:
The first component is injected into the cavity, which is part of the index plate. The preform is then pushed out and rotated. By moving the index plate back, the preform is placed on the other mold core and completely or partially overmolded with the second component on both sides. At the same time, the second cavity can be filled with the first component.
The sliding table technology can be used for all 2K components in which the preform is partially or unilaterally exposed. This technology is particularly suitable for unilateral overmolding of small quantities in prototype production or small series.
Process technology:
The mold consists of a core side and two cavity sides. First, the first component is injected into the mold. The mold is then opened and the core side is pushed onto the second cavity half so that the second material can be injected. The two components are injected sequentially.
The transfer technology is used for all 2K components in which the preform must be free on both sides. All design grades can be covered with this multi-injection technology.
Process technology:
The preform from the first cavity is removed by a robot and inserted into a cavity. The second component is injected after the mold is closed, while the other available cavity is already being filled with the first component.
