Paraffin wax Paraffin wax, also known as crystalline wax, is through distillation after solvent refining, solvent dewaxing or by wax freezing crystallization, press dewaxing to make wax paste, and then by solvent deoil or sweat deoil, and supplement refined by flake or needle crystal. According to the different degree of refining, it can be divided into three kinds: full refined paraffin, semi-refined paraffin and crude paraffin. Each type of wax is divided into different varieties according to its melting point. The melting point of paraffin wax is an important indicator for judging the brand name of paraffin wax. For example, the melting point of No. 50 paraffin wax should not be lower than 50°C. The melting point of paraffin is also important for practical applications. Hard wax with a melting point of not lower than 52°C is suitable for making candles. If you use paraffin wax with a melting point lower than 52°C to make candles, it will become soft and curved in hot weather and will stick to each other. However, for paraffin wax used to make matches, you only need to use paraffin wax with a low melting point because it is used for soaking. Matchstick, which makes the matchstick easy to burn. 1. The main composition of paraffin Paraffin wax is mainly composed of normal (straight chain) alkanes above C15, and also contains a small amount of isoparaffins or cycloalkanes with long side chains. 2. The melting point of paraffin The melting point of paraffin wax is a main indicator for judging the grade of paraffin wax. For example, the melting point of No. 58 paraffin wax should not be lower than 58°C and not higher than 60°C. 3. The stability of paraffin wax Stability is divided into light stability and thermal stability. Petroleum wax should have good thermal stability and light stability. Otherwise, if it is exposed to hot air or direct sunlight for a long time, the paraffin wax will gradually oxidize and deteriorate, the color will become darker, and even the odor will become stronger. Fully refined and semi refined paraffin wax is used widely, mainly used as candles,board,plastics,rubber and other commodity(like waxed paper ,crayons,candles,carbon paper) of the component and packing materials, baking container with dressing, used for electrical components, insulation rubber aging resistance and increased flexibility, etc.

Business projects: precision molding grinding, precision EDM, CNC wire cutting, precision milling machining. Independently research and develop and design automation production machine, to solve the human bottleneck problem and production obstacles for clients. Customized customer demand, research and develop automated production in accordance with the customer production planning. Automated assembly production, share client capacity, OEM production to finish customer delivery. We cooperated with the businesses from different countries and regions Japan ABLE, Belgian Accuritas, Taiwan Cheng Wei Precision Industry Co., Ltd., Cheng Ming Electronic Science and Technology Co., Ltd. (Dongguan) Our company wants to establish long-term cooperative relationship with the following types of foreign enterprises: Electronics, automotive, electrical machine, electrical equipment, instrumentation, home appliances, communications and other industries. DESCRIPTION OF CNC HIGH-SPEED MILLING MOLD PARTS What Are The Main cnc milling metal parts Column and base The column and base support the remaining parts of a milling machine, and the spindle is lubricated by an oil reservoir and pump in the column. The base supports the column and includes a coolant reservoir and a pump for coolant delivery during machining operations. Knee The gearing mechanism is housed inside a knee. Dovetail ways connect the knee to the column. A vertical positioning screw, often known as an elevating screw, supports and adjusts it. The elevating screw moves the knee up and down by raising or lowering the lever using a hand or power feed. Saddle and Swivel Table The table is supported by the saddle, which is on the knee. In horizontal milling m/c, the saddle slides on a horizontal dovetail on the knee, and the dovetail is parallel to the spindle’s axis. The saddle swiveled (revolved) horizontally in both directions, and the swivel table was attached to it. Spindle A milling machine’s cutting tools are held and driven by the spindle. It is supported by the column and is positioned on bearings. An electric motor drives the spindle using gear trains located on the column. The spindle face, close to the table, is machined with an internal taper. The front face has two keys that give a positive drive for the cutter holder or arbor. Table A table is a rectangular casting that sits on the saddle’s top. The table is used to keep the work in place or to hold work-holding equipment. Several T- slots are available for storing work and work-holding devices (jigs and fixtures). It can be powered or operated by hand. It engages and turns the longitudinal hand crank to move the table by hand. It engages longitudinal direction feeds control lever to move it by power. Over Arm/ Overhanging Arm On the upper face of the column, there is an overarm, which is a horizontal beam. It could be a single casting that slides on the top face of the column’s dovetail manner. Ram In a vertical milling machine, the ram is an overhanging arm. The milling head is attached to one end of the ram, positioned on the top of the column. If you need any kinds of precision plastic molding, please contact us, as a professional precision moulding company, Fangling is willing to offer you high quality products.
