CM SERIES VOLUMETRIC DOSER
Â
   CM series volumetric dosers are suitable for auto-proportional mixing of virgin materials, regrinds, master-batch or additives. Brusheless DC motors are adopted. According to the proportion and data set up, its micro-computer control system turns into referred speed, drive the precise SS304 dosing screw by the coupling, throw out the required material into injection machine. Its error value is below 1%. Give a total of six models with output ranging from 0.1~100kgs /hr. Double color dosers can be assembled from two single color dosers if required. Five components automatic mixing can be realized if customers adopt four color dosers.

Features:
* Dosing screws are chrome plated for durability.
* Unit is comprised of standard modules for ease of cleaning, disassembly and interchangeability.
* Blender is a standard equipment for double color doser to make the material evenly mixed, while also a optional equipment for single color doser to do so.
* Main material hopper is a standard equipment for double color doser. It is optional for single color doser.
* External signals can be directly interfaced with control box.
* The current operation mode can be recorded, unaffected by power failure so operation would be returned to normal when power is on.
* Forced material cleaning is convenient to replace masterbatch.
* Applicable on extrusion machines, just need to make a few wire replacements.
* Rotating speed can be automatically adjusted according to extruder processing speed, which maintains the fixed proportion of masterbatch.
* 50 units of parameter recipes are available for permanently recording the period of material discharging and finished products weight (for extruder, it is max. Throughput per minute).
* Use brushless DC motor and free from maintenance.
* Both master blockage and overload can be detected, then machine will halt and sound alarm.
* Based on customers demand, some mold cycles can be set to add additives periodically so that micro-metering can be achieved.Â

Zinc Alloy Die Castings
The features of Zinc alloy die castings are as follows:
1). High Density;
2)Good Casting performance, complex shapes can be die-casting, precision parts, thin-walled castings smooth surface.
3). Good surface after finish surface finished, such as: chrome plated, spray, spray paint.
4) Melting and die-casting iron absorption, pressure-type non-corrosive, non-stick mold.
5) has good mechanical properties at room temperature and abrasion resistance.
6)Low melting point, melting at 385°C easily die casting.
Zamak 3: Zinc Alloy Die Casting have a good fluidity and mechanical
properties. Used in casting of low mechanical strength, such as toys,
lamps, decorations, some electrical parts.
Zamak 5: Zinc Alloy Die Casting have a good mobility and good
mechanical properties. Applied to certain requirements of the mechanical
strength of castings, such as auto parts, electrical and mechanical
parts, mechanical parts, electrical components.
Zamak 2: Zinc Alloy Die Casting have a there are special requirements
for mechanical properties, hardness, wear resistance, dimensional
accuracy requirements of the mechanical parts
ZA8: Zinc Alloy Die Casting have a good flowability and dimensional
stability, but less liquid. Used in die casting, small size, accuracy
and mechanical strength demanding workpieces, such as electrical
appliances.Superloy: the best mobility, applied to the die-casting
thin-walled, large-size, high precision, complex shape of the workpiece,
such as electrical components of the box.
Different zinc alloys have different physical and mechanical
properties, such as die casting design provides room for choice. The
same time, the choice of the zinc alloy is more important to select what
kind of zinc alloy, mainly from three aspects to consider.
1,Zinc Alloy Die Castings have their own purposes, need to meet the performance requirements.
(1) mechanical properties, tensile strength, when the material fracture
resistance;Elongation, brittleness and plasticity of the
measure;Hardness is the resistance of the material surface is pressed
into a hard object or friction caused by plastic deformation.
(2) state of the working environment: temperature, humidity, media contact with the workpiece and air tightness requirements.
(3) precision: accuracy and dimensional stability can be achieved.
2,process performance of Zinc Alloy Die Castings:
(1) casting process;
(2) mechanical processes;
(3) surface treatment.
3, Economic good: the cost of raw materials and production equipment
requirements (including smelting equipment, die casting machine, mold,
etc.), as well as production costs.
