Advantages:
A ram extruder is an extruder where, instead of extrusion screw, a ram or plunger is used . The ram extruder was the earliest extruder to be used in the plastics industry. This typical process is applied for producing profiles, sleeves, rod, block, tubing, lining sheet bars, etc. The ram extrusion process is very effective for specific materials like PTFE which are not extruded successfully using screw extruder.
In this process plastic material in powder form is gravity fed into a chamber. In the extrudating chamber the resin powder is heated on sintering temperature. Ultra high molecular weight polyethylene, becomes gelatinous as it melts so it can be extruded with this type of processes. A hydraulic ram pushes the resin materials like PTFE, UHMW, etc. from the chamber to the die. The die actually gives the shape of the desired plastic like a rod, tube or a profile shape with the requisite internal or outer diameter. When the material comes out of the die, it moves the length of the conveyor. The profiles can be manufactured endlessly and cut by the continuous extruding of each length.
Types of Machines:
There are two types of ram extrusions- the vertical ram extrusion and the horizontal ram extrusion. Whatever be the type of ram extrusion, the resin feed, compaction or performing, sintering and cooling are all the same. But the extrudates quality depends on various parameter like the design of the extruder, powder properties, extrusion rate, pressure and temperature.

One key importantadvantage of PTFE Rod is its operating temperature range,it can easily outperform other engineering plastics by being able to perform continuously at-250°C, right up to an amazing 250°C. Another important advantage of PTFE Rod is its outstanding co-efficient of friction, PTFE is in the record books ashaving one of the lowest friction values known to man. PTFE also has excellentacid and chemical resistance. Another feature of PTFE is its ability to set byor due to compression.
PTFE has excellent electrical resistance. PTFE is alsowater repellent and is often used in the manufacture of modern high performing,water repellent and breathable clothing.
PTFE is excellentfor low friction bearings, bushes, rollers and pulleys. PTFE is also almostexclusively used in cryogenic components due to its ultra low operating temperatures.PTFE Rod is regularly used for seals. PTFE Rod has become a very important engineering plastic used within the aerospace industry and aeronautics.
PTFE isoften used within the food industry companies. Another useful application overthe years has been in the use of product or component handles due to its resistance to heat and heat transfer. When an application for electrical resistance becomes too high for other materials, PTFE Rod can fill a very important gap.
Because PTFE hassuch a low co-efficient of friction it offers a material that when used willreduce load and drag in bearings to improve efficiency and reduce frictional losses and PTFE will outlast other materials. Because PTFE Rod will set due to compression, PTFE seals will conform to mating components resulting inexcellent sealing capacity. PTFE is reasonably easy to machine which helps withreduced machining costs and increased capacity and efficiency. PTFE isresistant to most acids allowing this material to be used in aggressive environments to where such materials as Polypropylene are unsatisfactory.
