Manifolds - Import export

The new 8C compact manifold is especially impressive for its small size. In the single-sided version it can have 2 - 5 outlets, in the double-sided version 2, 6, 8, or 10 outlets. The outlets can be designed to customer specification either with integrated connections for flexible tubes series 1+ in sizes DN04/06 or DN06/08, or with threads G1/8" or G1/4". The side endpieces (input/output) of the manifold can be sealed or fitted with G3/8" or G1/2" threads.

The 8B standard manifolds in various designs and materials. Due to the special design, several manifolds can be easily connected in series. Depending on the application, the media can be either distributed directly or shut off as required using the appropriate fittings.

Compact valve manifolds with low piping effort, reduced maintenance time and minimize investment costs. A connection system well known from the field of hydraulics and adapted to the respective application, allows for the intelligent combination of several valves in a customerspecific manifold. All necessary connections between the individual process valves are integrated in the manifold.

Control valves and directional valves clear, block or change the flow direction of the medium used. They control the direction of the volume flow, i.e. the exit direction of a cylinder, and through start-stop commands the travel distance of the stroke. Our product range includes manual, pneumatic and electro-pneumatic actuated valves in 3/2-, 5/2- and 5/3-directional design. Directional valves acc. to NAMUR, supply units, base plates, logistics modules and two-handed safety control valves add to the assortment.

• Mold measurements up to 4 x 2 x 1 m • Does away with elaborate and expensive mold set-ups • Short throughput time (a few days) • Sand molds correspond 1:1 with CAD model • Structures can be designed in accordance with requirements, without having to watch for draft angles or undercuts • Special sands prevent casting problems • Surface quality can be adjusted through use of different sands • Coarse-grained sands for high gas permeability • Considerable flexibility with changes in geometry, without additional expenses • No storage or maintenance of patterns • Cost savings particularly for complex molds and batch sizes of 1 to several hundred pieces

Parting agent at foundry operations injection moulding, blowing and extruding processes of plastics and elastomer Avoids the sticking of e.g. adhesives and sealing excess or water wetting Sliding agent against noisy rubbing of plastics, elastomers and metals together or against each other Lubrication of cutting edges in the paper, cardboard, veneer layer and textile processing machines For easy retracting of plastic and rubber profiles, e.g. in the door and window production Advantages and benefits High efficiency because of excellent netting of the surface and building of extremely thin lubricating films Separating effect with antistatic properties Manifold applications for permanent lubrication, protection, maintaining and impregnation Neutral behaviour against plastic and elastomers Resistant against water and atmospheric influences NSF H1-registered

Square cartridge heaters are used where much power has to be installed near the surface of a tool, e.g. in cutting knives, sealing stations or hot plates. With a soft, malleable condition in stainless steel or nickel sheath square cartridge heaters can easily be pressed into common milled rectangular grooves. Apart from the advantageous heat transfer over ¾ of the sheath, it is not necessary to cement or cast in the heater which is imperative for round cartridge heaters. Unlike tubular heaters which are also available in square sections (see chapter Flexible Heating Pipes), the square cartridge heaters have the termination on one side and can be loaded with 16W/cm² (2.5W/in²) due to their special inside construction.

Square stainless steel tubular heaters BASE-flex (1.4541) are a reliable industry standard for the use in heating platens and manifolds. In contrast to traditional tubular heaters with a round section which have to be bent by machines, square BASE-flex can be fitted into any rectangular groove with simple hand tools. Moreover, the square shape results in a bigger heat emitting area of up to 80% compared with a corresponding round section. Finally, the easy manual mounting saves the usually high technical expenditure for casting-in / soldering / cementing of bent round tubular heaters. A soft version of the BASE-flex, the NICKEL-flex (2.4068) is available as special execution. Due to the soft, easy to form nickel material, the NICKEL-flex is suitable for manual mounting with hand tools in round sections, too. Furthermore, Nickel has a better capability to conduct heat compared with stainless steel.

HotCoils have a larger cross-sectional area and are thus capable of greater power than MicroCoils. For this reason they are used in hot runners with adequate space and where high heat densities are required. Owing to the large number of variants and for cost reasons, the sheath material for HotCoils is stainless steel - the standard for the market and thus also for Freek. HotCoils are large enough that thermocouples can be integrated into them. Our standard here is Type J (Fe-CuNi; red/blue), while Types J and K are also available conforming to the IEC and ANSI standards (see colour codes). Since the measurement point of a built-in temperature sensor is situated in the heater and never where the heat is actually required, a HotCoil with a thermocouple makes particular sense where the application allows the use of larger processing (temperature) windows or where the installation location or the design requires protection against overheating.

Valves & Manifold

Whenever several valves are to be used in a confined space and with minimal piping, a module or strip solution is recommended. In contrast to single piping, the expense for valve piping, fittings, working time, and possible leaks is almost cut in half.

Our standard range was developed with regard to technical and economic aspects especially for the increased requirements in machine and plant manufacturing. Steel and aluminum manifolds, adapter, blind and intermediate measurement plates are in stock at any time, allowing us to quickly meet your urgent requirements for various pressure stages. All plates have corrosion protection (zinc-plated or anodized).
