PTFE Ram Extrusion Line

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.
PTFE Ram Extrusion Line
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.

Blow Molding Machine

Blow Molding Machine is a shape forming manufacturing process that involves forcing material into a die to make other shapes with that matetial. It’s like play dough. Imagine having play dough and pushing it through one of those tools with all the holes. You end up with play dough spaghetti. This is an example of extrusion. You can achieve a lot of different stock sizes and lengths by extruding. Like play dough.
The actual process involves a lot of math and hard work and a lot of set up. You start off with the material. Metal is typically used when doing extrusion. Then that material is pushed through another piece of stronger metal with a shape cut out of it where the material is forced out, creating that shape.
Blow Molding Machine is perhaps the simplest type of blow molding. A hot tube of plastic material is dropped from an extruder and captured in a water cooled mold. Once the molds are closed, air is injected through the top or the neck of the container; just as if one were blowing up a balloon. When the hot plastic material is blown up and touches the walls of the mold the material “freezes” and the container now maintains its rigid shape.
Blow Molding Machine allows for a wide variety of container shapes, sizes and neck openings, as well as the production of handleware. Extrusion blown containers can also have their gram weights adjusted through an extremely wide range, whereas injection blown containers usually have a set gram weight which cannot be changed unless a whole new set of blow stems are built. Extrusion blow molds are generally much less expensive than injection blow molds and can be produced in a much shorter period of time.

Horizontal Automatic Plastic Moulding Machine

Automatic molding, a semi-automated form of compression molding, is the process Sunkoo uses for the manufacture of medium-volume to large-volume net molded and near net molded Plastic components. The automatic molding process requires dedicated tooling, typically requires minimal operator intervention and plastic parts can be fabricated relatively rapidly.

With the use of precise tooling and processing, parts manufactured using the automatic molding process can be produced to relatively close tolerances, but not to the accuracy of a fully machined part. Components are economically molded by utilizing a process of automated filling of the die cavity, applying pressure, and part ejection.

Full automatic blow molding machine for handled bottle production,this model boasts with full automation,high intelligence,stable fuctioning,simple composition,high efficiency,low cost,no contamination in production,up to National Hygienic Standard,widely applied in food,beverage,cosmetics and pharmaceutical field,etc,especially find great applications in edible oil production industry.

PTFE gasket making machine

PTFE gaskets are used in many industrial applications, especially the following:

1, Compressor – High temperature and surface-wear resistant sealing gaskets.

2, Electric Motor – Sealing gaskets for components that require corrosion-resistance, exposure to high and low temperatures and high surface wear.

3, Medical Component – Seals for electronic instrumentation using materials that provide secure seals and long product life.  Specialty gaskets, especially miniature sizes, are required for many medical devices.

4, Petrochemical – Gaskets for process equipment that are resistant to corrosive fluids, temperature extremes and surface wear.

Horizontal PTFE Extruder

Horizontal PTFE extruder gives our customers great flexibility while occupying a minimum amount of floor space.

Horizontal PTFE Extruder
