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.

Calcium Carbonate (CaCO3) is one of the most widely used Mineral Fillers in the Plastics and Polymer industry, and its use in rigid packaging has increased significantly over the years¦...As an additive in Plastic and Polymer compounds, CaCO3 helps decrease surface energy and provides opacity and surface gloss, which improves surface finish. In addition, when the particle size is carefully controlled, CaCO3 helps increase both impact strength and flexural modulus (stiffness). Once thought of simply as a resin extender, the addition of calcium carbonate in plastics has been shown to contribute to increased performance, improved processing, and improved sustainability of the finished part. Calcium Carbonate may be used with a myriad of thermoplastic resins. Polypropylene compounds are often filled with calcium carbonate to increase rigidity, an important requirement for operations at high temperatures. In PVC, calcium carbonate is used with flexible compounds such as tubing, wire and cable insulation, latex gloves, trash bags and in rigid compounds such as extruded pipes, conduits and window profiles. Both calcium carbonates and coated calcium carbonates contribute to the ultimate performance properties of this wide variety of piping applications. Product choice depends on the specific application and the property requirements of that application. For maximum property development and formulation flexibility, surface-treated carbonates are designed to give good dispersion along with excellent incorporation in the polymer matrix. Calcium carbonate improves the base properties of polyvinyl chloride by adding stiffness to the polymer matrix and improving impact resistance as particle sizes become smaller. Calcium Carbonate also improves compounding performance by helping disperse various ingredients into the PVC powder blend and improves processing by making polymer flow more homogeneous. Calcium Carbonate filler is one of the most innovative solutions ever developed in this industry. Calcium carbonate filler not only functions in improving the quality of final plastic products but also helps plastic manufacturer reduce as much production cost as possible, hence gain more profits. In general, CaCO3 powder is widely used as a plastic additive in industrial production for several reasons, Check out five great reasons why you should consider using Calcium Carbonate:
Product description Polythene insulated jelly filled, un-armored telecommunication cables (10 to 2400 pairs with conductorsÆ dia of 0.4mm, 0.5mm, 0.6mm and 0.9mm) are manufactured on pakistan telecommunication company specifications lw-33 with reference to various international standards and specifications. Premier cables offers a wide range of telephone cables. Application This cable is usually used for direct buried applications for distribution in the exchange areas as local network and interexchange applications. It is a cable with solid polyethylene insulated unit twin jelly filled construction. Construction Conductor: Solid annealed copperith conductor sizes of 0.4 & 0.6mm. Insulation: Colored high molecular weight solid high density polyethylene. Color coding: Cables are fully color coded in accordance with pic even count color code. Twining/pairing: Two colored insulated conductors are uniformly twisted together to form a pair. Varying lay length is designed to minimize the cross talk and capacitance unbalance. Stranding / cabling: Twisted pairs are assembled into unit of 25 pairs. When desired for lay-up reason, the units are divided into two or more sub-units, which are bind with durably colored polyethylene tapes to form a compact and circular cable. Filling compound: The water resistant filling compound is applied to the air space within the cable core. Core covering: A non-hygroscopic and dielectric polyester tape and water blocking tape are applied helically having a suitable overlap. Flooding compound: Sufficient flooding compound is applied between the core wrap and shield.
