Coating/Dispensing platform

Alpha 6 is the new innovative and compact processing platform for a wide range of coating and dispensing applications. The system is outstandingly easy to use and highly flexible in meeting many different requirements. The machine is designed as a self-contained working cell that can be used for both coating and dispensing various media, together with other customer-specific applications, such as surface treatment with atmospheric plasma.

Handset for laboratory and sample production

The TM 2000 series offers electronically controlled hand dispensing devices for the processing of hotmelt polyamide. Mounting stand and timing ensure reproducible results.

Technical data:

From specimen moulds in the development stage to highly complex tools with slides and ejection systems, different gate techniques or gateless hot runner systems – we equip all of your needs in terms of hotmelt tools. The specimens are developed and made by experienced toolmakers and are always provided in reproducible quality.

Hotmelt moulding platform

The tool holder offers sufficient size for common standard mould sizes with horizontal injection. TM 2200 with its vertically moving cylinder can be adjusted to many different tool heights. The standard height adjustment for moulding head TM 1010 permits the use of different separation levels.

Hotmelt process unit

Due to its unique, modular layout, the processing unit TM 2300 offers a very flexible and compact solution to fit your hotmelt application perfectly.
The system comes either with a manual sliding table (to give you the most space for your tools) or else equipped with a cross sliding table. Both can work with single or multipoint gating. Injection can be done vertically or horizontally.

As stand-alone devices, the processing systems of the TM 2500 series offer an ideal and economical entry into the hotmelt production of small and medium-sized batches. The freely accessible tool area with its maximum room for manoeuvring is particularly suited for the cable-manufacturing branch.

Hotmelt moulding platform

The two units in the modular moulding platform TM2500- TWIN communicate with each other and are ideally designed for optimum supplies to both platforms with just one material feed point.

While moulding station 1 is busy with the moulding process and cooling time 1 after closing the mould, moulding station 2 can be prepared by inserting the parts and then triggering the injection and cooling cycle. A switchbox TM 1300 is used to ensure that the moulding cycles are started in succession.

As a low-cost standard version, the TM2500-3 moulding station with tank unit TM1004 is the ideal entry level for hotmelt processing. The open design of the mould holder offers sufficient free space particularly when moulding cable systems or partially moulding foils or more complex components.

The optional use of a switchbox makes it possible to operate two TM2500-3 platforms with just one material supply. This results in the greatest possible production capacity for one operator with ideal cost effectiveness.

Hotmelt process unit

The processing systems of the TM 3500 series were developed for stand-alone operation. They are designed for small to medium batch serial hotmelt moulding.
The modular design for several tool holders enables efficient production. A set of tools comprises 2 bottom halves of a mould and one mould top half. While the moulding process is operating automatically on one side of the sliding table, the finished part can be removed from the second bottom part of the mould and a new part inserted. The table is slid manually.

Hotmelt moulding platform

The TM4500 moulding station is designed for low-pressure injection moulding specifically in medium-sized series.
The lower sub-moulds alternate on an automatic sliding table under the top mould. A Plexiglas safeguard protects the operator while the procedure takes place. Tool clamping is pneumatic up to a clamping force of 1400 kg with maximum occupational safety thanks to the convenient two-hand control.

Technical data

Hotmelt moulding platform

The TM6800 injection moulding machine is designed specifically for coating inserted parts in mass production.

The TM6800 is designed for processing thermoplastic materials in the temperature range of up to 250°C at max. 200 bar. The machine offers maximum possible flexibility for the tool holder and can be equipped with either a horizontal sliding table for the sub-moulds, the drawer version bringing the sub-moulds to the operator or with a tooling robot moving the sub-mould.

Technical data

Material preparation

Either all the material is heated in an oven or only the required amount is melted, provided by an extruder and conveyed to the injection mould.
