Thermoforming is a generic term for the manufacturing of plastic components through the vacuum or pressure forming processes. An overview of the single-sheet thermoforming process consists of heating extruded plastic sheet and forming the sheet over a male mold or into a female mold. Depending on what type of mold a customer selects, the thermoforming process allows the customer the ability to receive a part with the same aesthetic properties as an injection-molded part at a fraction of the tooling expense involved when you compare the cost in injection molding. There are many types of Thermoforming process is availble. For example single sheet thermoforming,Plug assisted,Pressure forming,Vaccumforming ,twin sheet thermoforming. Twin-sheeting is heating two sheets of plastic and then forming and sealing the two sheets of plastic together during the forming process.Materials like PVC, ABS, PETG, ACRYLIC, PP, HDPE can be thermoformed upto 10 mm thickness. In some cases, the twin-sheeting process produces parts that resemble a blow-molded part, but the twin sheeting process allows the customer to receive a higher quality, more aesthetic part also a two color part, if required.

PHB - Twin Shaft Bevel Helical Geared Motor consists of helical-geared industrial gear units with bevel stage input. Input and output shafts are perpendicular. PHB - Twin Shaft Bevel Helical Geared Motor is optimized for power density to achieve the highest rating at the smallest possible dimensions. But because high power density also means increased thermal load, the new products are provided as standard with various cooling options. Efficiency is further enhanced through the use of high-grade lubricants and sealings. Another advantage is the wide range of mounting possibilities: The units can be mounted on any side, directly to the motor flange or to the output flange, greatly simplifying their installation. Because these gear units can be mounted on any side, additional equipment, such as integrated or external forced lubrication or oil expansion tanks are available as accessories. We also offers tailored solutions for specific applications. Our standard range includes reinforced bearing arrangement or extended bearing distance for high radial load or agitator applications, backstops for single-direction applications such as conveyors or elevators, brakes for hoisting or moving applications, and shrink disks for alternating loads. Special solutions for extruder applications are provided for each size and ratio.
Sandwich Panels KRS Sandwich Panels consist of an insulation core with facings of flexible materials and are produced on a continuous laminating line using a two part polyurethane adhesive system. They are used in the building of insulated structures such as coldrooms, classrooms, distribution centers, freezers and abattoirs. The core materials that can be used are expanded polystyrene (EPS), Rock wool, PU/PIC, POLYPHEN and extruded polystyrene (XPS). The facing materials are pre-painted galvanized steel, Aluminum or GRP. The standard width of panels is 950mm, 970mm, 1000mm and 1150mm. Panels can be manufactured to any transportable length. The panels have a male female INTA lock system and various face profiles can be produced. The profiles included are: flat, fluted, shadow line, micro rib and raised rib. Advantages and Disadvantages of the different core materials EPS Core Panel Advantages It is the most economic form of insulation It is extensively used due to its insulation properties and high strength to weight ratio It has a high resistance to water absorption The flexible core is not easily damaged Its relative low weight makes panel installation an easy process Disadvantages When exposed to a fire the core material starts softening from 90Ì? C and the panels lose their structural integrity The core material ignites at 350Ì? C in air Rock wool Core Panel Advantages It has excellent thermal and acoustic properties It is fire safe It is chemically inert and CFC and HCFC free Disadvantages The price is higher The panels are fragile and need to be handled carefully The panels can delaminate with dynamic loading of excessive foot traffic The core materials are imported which adds 8 weeks lead time to the start of installation The high panel weight requires mechanical equipment for installation PU Cored Panel Advantages The panels are made using fully cured Polyurethane foam slabs They are CFC free but not HCFC free Although Polyurethane is not non combustible, it does not burn in the same way as EPS Polyurethane panels, when subject to fire, forms a carbonaceous layer which retards further flame spread and maintain integrity for longer Disadvantages Polyurethane core can break The panels need to be handled carefully When burning, the core of the panel emits toxic fumes (Cyanide gases)
