Each expansion joint is tailor made. Layers of material are assembled on a frame which conforms exactly to the required profile. Bellows type expansion joints incl. or without reinforcing rings/frames. Diaphragms Expansion joints for varying cross sections and transitions. Construction from round to rectangular Construction according to drawings Non-standard high temperature seals Compound movement

The number of patents awarded to KOREMA® such as SIMIFLON® reflects an ongoing commitment to long term development of specialty materials which have opened new horizons and perspectives for the future. SIMIFLON®, (light colored material) is designated foodstuff quality and certified according to § 177.2600/177.1550 CFR of US Food and Drug Administration (FDA) as well as to EU Regulations EU 2002/72/EG and EU 10/2011.

This is the most installed version of the fabric expansion joints (KOREMA® type A3 or AC3 as well as B3 or BC3). The name »flange-type« is used for expansion joints located between pipe or duct end flanges. For existing plants, the flange design varies according to customers’ requirements or depending on the constructed steel design. For innovative designs KOREMA® will identify the suitable technical and economical solution. Special design: supplied as »open« multilayer expansion joint. On-site service available exclusively from the KOREMA® service team. Insulation is incorporated to protect the expansion joint against abrasion as well as for thermal insulation. The choice of insulating material, either mineral wool or ceramic felt, depends on the design temperature. For operation at or below dew point, a vulcanized elastomeric layer is available. Pre-assembled units, complete with liners and clamp bars, are available.

The belt type is the preferred choice for large diameter ducts. Delivery available with insulation pre-installed for high temperature applications. Insulation depends on temperature level of the medium. Insulation is necessary to protect the expansion joint from abrasive media. Corners of rectangular expansion joint frames should be radiused. Delivered as open-end construction for site completion. The final splice will be made on site. The storage and installation instructions as well as the necessary adhesives are included with each shipment. Pre-assembled endless units are complete with appropriate steel components which may be in several parts depending on the size. KOREMA®’s “on-site service” is available for site supervision.

Machining is a generic term for various manufacturing processes such as milling or turning used to give workpieces a specific shape by removing excess material via mechanical influences. According to the wishes of our customers, we can realise high surface qualities with sealing surfaces as well as a dimensional accuracy of 10 μm. Machining can be used on a variety of different materials: Stainless steel Non-ferrous metals Nickel-based materials Titanium materials Plastics

Deep-drawn tubes from stainless steels (with a closed side or open) Deep-drawn tubes from non-ferrous metals as bronze, brass,... Seamless sleeves made with stamping processes Ultra thin-walled tubing in Beryllium copper or other special alloys Annealing services in vacuum furnaces Washing technologies for soap and oil The precision tubing is needed at Mera Bellows to manufacture seamless metal bellows.

We have minimized the weight of our manifolds without restricting ist vital functions and thus enable high energy savings for our customers. In addition, our manifolds are known for an uniform temperature distribution and no dead spots in the flow channels preventing the resin from deterioration.

No sprue losses with the perfect cold runner system. Material costs, expenses due to scrap and additional working hours in post-processing can be reduced considerably by using our RUDIZ system.

All of our controllers are characterized by user-friendly operation (in various languages) and maximum precision. They are shielded from interfering signals and work with little noise. Our controllers are work with Seiki hotrunners or hotrunners from other manufacturers. We have experience in using our controllers with the most of the injection molding machines commonly used in Europe.

Our hot-halves complete systems mean all-round service for you, we are at your side from construction to the final sampling at your factory and keep you up to date with simulations.

Seikis valve gate nozzles are available with independent heating of the nozzle tip and the shaft. The can be controlled individually and, therefore, synchronized with the injection for less wear and tear and a clean closure of the nozzle.

Our patented Spear nozzles with thermal-sealing via the separate tip-heater open up new possibilities in injection molding, especially when processing glass fiber or carbon fiber reinforced resins.
