This press is used to manufacture large-format rotor blades using the RIM process for the production of air-water recooling systems for petroleum processing. For ergonomic operation, the upper part of the tool, measuring up to 5,000 x 1,600 mm, can be swiveled 90° toward the operator.

High-performance thermoplastics are processed on an area of up to 2,000 x 1,000 mm. The connected IR preheating oven brings the components to a temperature of up to 450°C in the shortest possible time. The subsequent component transfer to the press takes less than 6 seconds.

The WKP 6 000 S is a high-precision hydraulic press that has been specially designed for the development of thermoforming and consolidation processes. Equipped with electrically heated heating plates, it enables precise temperature control up to 450°C. Maximum process speed is ensured by high-speed handling, which transfers the clamping frame including the raw part from the infrared oven to the press at maximum speed. It takes less than 4.5 seconds from leaving the oven to completely closing the press – ideal for dynamic processes in research and development. This versatile press is designed not only for processing composite materials, but also for a wide range of other materials, including particle foams and high-performance metal alloys.

The WKP 5 000 S is a high-precision hydraulic press specifically designed for the development of thermoforming and consolidation processes. Equipped with thermal oil-heated press platens, it offers exceptionally accurate temperature control of ±0.5K – even at platen temperatures of up to 410°C and heating rates of 20K/min. To ensure maximum process speed, a high-speed handling system rapidly transfers the clamping frame including the blank from the infrared oven into the press. From the moment it leaves the oven to the complete closure of the press, less than 3 seconds elapse – making it ideal for dynamic process workflows in research and development.

With transfer handling, components presented outside the press can be transferred very quickly and with only a minimal press stroke. This reduces the open time/machine time of the press to a minimum, which maximizes the output. The press can be interlinked with the upstream process or operated manually for small series / prototypes. With a quick-change mold system, a wide range of mold sizes and therefore component sizes can be processed and either components can be “nested” with 2 cavities each or large friction discs can be hot-bonded.

We boost / automize your press-processes. A previously manual process becomes a fully automated process: Fully automatic loading and unloading of fragile components into / from a hot bonding press for pressing / calibrating the components with the highest possible precision. Up to 4 hours unmanned production: With the solution shown, the system in the application example can produce completely independently for 4 hours. No interruption of the production process necessary. The lock principle even ensures, that the magazine can be emptied / refilled during ongoing production.

The system is specially designed for the fully automatic production of cylinders or hollow cylinders made of free-flowing PTFE. Since free-flowing PTFE loses its pourability at temperatures above 18°C, the entire material feed system is air-conditioned to ensure that temperatures remain below 18°C.

The entire system consists of a powder press and an isostatic re-densification unit. The special feature is that both systems are controlled by a common control and hydraulic system. This saves space and investment costs. The maximum compaction pressure in the press is 2,000 bar, and as much as 3.500 bar in the downstream isostatic pressing.

The continuous press system consists of two hot presses, two cooling presses, automatic loading, automatic product unloading and automatic release agent supply. The high degree of automation of the system allows the entire system to be supervised by just one person. There are always 5 moulds in use at the same time. 4 moulds in the two hot and cooling presses. The fifth mould is located outside the press for unloading, cleaning, spraying release agent and loading.

The large-format molds are filled fully automatically via an extruder. The extruder is also suitable for compensating mass loss during cooling in the mold using the “holding pressure” function. The maximum product weight is 500 kg. The state of the art for this process is a variothermal process with a very large variothermally moved weight. Due to the fact that the material does not have to be melted in the mold, it is possible to work with significantly lower maximum temperatures in the mold. This saves cycle time and energy.

Beech veneers are pressed fully automatically into highly compressed laminated densified wood on the three-daylight press. In addition to the high specific pressure, a variothermal process control with good temperature distribution is a success factor. The temperature control is done by a pressurized water temperature control system

Central ejector at the bottom for easy and simple ejection of products. Adjustable mould change consoles to change different pressing tools as quickly and easily as possible

The vacuum chamber press is used to manufacture large gaskets and large rectangular parts. The heating plate and vacuum chamber are therefore square. The sliding table is used to move the lower part of the mold together with the lower heating plate in front of the machine, thus ensuring good ergonomics for the operator in this position.

The vacuum chamber press has been specially developed for the production of large elastomer seals. The vacuum chamber reliably prevents unwanted air pockets in the seal. The fact that only round tools are used on this machine allows for a round heating plate and a round vacuum chamber. The main advantage of this configuration is significantly improved accessibility and thus significantly improved ergonomics for the operator, especially when inserting blanks into the lower tool. This ergonomic advantage is particularly beneficial for tools with a diameter of <1500 mm. Another advantage of the round heating plates is that the heating plate size can be reduced by more than 20%. This saves energy.

Including the press closing time, the entire process takes less than 5 seconds.

Wickert supplies fully automatic press systems for calibrating and hot bonding these friction discs, which enable both maximum precision in temperature control in the tool and maximum geometric precision in the tool, which in turn has a positive effect on the thickness variance of the friction lining itself and not only on the reliable bonding of the friction layers to the steel carrier. Depending on the desired output quantity, the presses themselves can be operated with the corresponding automation concept in “nested bonding” with several cavities or individually manually in a single-station concept. The traceability of production and process data, which is transferred to the customer's higher-level MES systems, plays a key role here.

For the production of a combination of a multi-daylight press and an automated loading and unloading device, the open time of the press can be reduced to a minimum. In addition to high-performance temperature control, this is a key factor in increasing system efficiency.
