Fixopan offers various models of pulverizer, also known as grinder or size reduction equipment, of high quality sturdy machines, which ranges from 40kg-300kg/hrs The models of pulverizing machine ensure the production of pulverized material from plastic granules for the manufacturing of high quality final products. Fixopan pulverizer can pulverize LDPE, LLDPE, HDPE and various thermoplastic materials and can offer to develop other kinds of pulverize for different materials on request

Fixopan pulverizers has fully automatic operations with predetermined sequence of operations such as Automatic granule lifter, Automatic on and off feeder, Automatic controls of mill temperature etc. The Pulverizer constitutes of high quality, maintenance-free, efficient components, like the Pulverizer Blade

Auto-cut-off the machine in case of any sequence fault. Pulverizer are available in various configurations like single mill, double mill, horizontals mill (to be introduced). With various designs, sizes and shapes of pulverizer blades. They are very special designs and are being approved by our in-house quality control and testing departments after going through rigorous tests and routine check-up procedures.

Shuttling Arm Rotomolding Machines - FIXOPLUS

2006-09-15T00:08:00.000-07:00

Fixoplus is a highly efficient machine and gives even heat distribution with a very good hot air recirculation, using minimum power and fuel. FixoPlus Rotomoulding Machine is versatile for producing any kind of simple or complex Roto parts e.g. water tanks auto dash- boards or rear mud-guards, highly ribbed large septic tanks, double walled parts etc.

Fixoplus is highly fuel/power efficient giving optimum time cycle using an Automatic system, designed to give accurate timing for heating and cooling. Fixoplus is modular and double indexing, where the machines can have a stationary oven with one or two arms or configured to move oven mono-axially and accept arms from one to as many as ten arms. This also gives the freedom from chronology of arms. The conventional multi arm machine normally is designed so that the arm one has to be followed by arm two and then by arm three and again arm one (on three arm machine). Fixoplus could be running in any random programmed order. There are many unique features in the machine for the benefit of the Roto molders.

A typical two arm, Fixoplus could produce 1 00 tanks in eight hours, using designs where the lids are molded along with the tanks. This could mean a production weight of 1.3 tons or 40,000 overheads, administration, labour, power, fuel, etc. is nearly the same as a smaller rock and roll machine or a lower technology machine, where the output may be one third. The machine is very economically

Rotational Moulding

Rotational moulding
we at fixopan global doing rotaional moulding in india
it is a process used for producing hollow plastic products. By using additional post-moulding operations, complex components can be produced enabling the process to compete effectively with other moulding and extrusion practices.
Rotational moulding differs from other processing methods in that the heating, melting, shaping, and cooling stages all occur after the polymer is placed in the mould, therefore no external pressure is applied during forming.

This provides the following advantages:
• Economically produced large products
• Minimum design constraints
• Stress-free products
• No polymer weld lines
• Comparatively low mould costs

The Process
The Rotational Moulding process is essentially split into four operations:

Charging Mould
A pre-determined amount of polymer powder is placed in the mould. With the powder loaded, the mould is closed, locked and loaded into the oven. The powder can be pre-compounded to the desired colour.

Heating & Fusion
Once inside the oven, the mould is rotated around two axis, tumbling the powder – the process is not a centrifugal one. The speed of rotation is relatively slow, less than 20 rev/min. The ovens are heated by convection, conduction and, in some cases, radiation. As the mould becomes hotter the powder begins to melt and stick to the inner walls of the mould. As the powder melts, it gradually builds up an even coating over the entire surface.

Cooling
When the melt has been consolidated to the desired level, the mould is cooled either by air, water or a combination of both. The polymer solidifies to the desired shape

Unloading/Demoulding
When the polymer has cooled sufficiently to retain its shape and be easily handled, the mould is opened and the product removed. At this point powder can once again be placed in the mould and the cycle repeated.
