BKG underwater pelletizer is superior in the manufacture of high performance engineering plastics and specialty polymers.

Abandon Trial and Error Method, Simulate Prediction 

Adoption of pelletizing die plate with independent temperature control modules ensures uniform temperature of the melt in the orifice, with a temperature difference of less than ±1℃. Use FEA finite element analysis to analyze the thermal stress distribution of the pelletizing die plate and improve the location of localized overheating. Eliminate melt deterioration, bubbles and yellowing of pellets due to temperature field temperature imbalance.

Die plate design, no longer a trial-and-error model, but a scientific system based on simulation measurement. Avoid empirical errors and reduce development cycle time by 50%. Improve the efficiency of underwater pelletizing systems and pellet quality.

Database Support Selection

The key to die plate design: orifice parameters, density of outlet distribution, length-to-diameter ratio (L/D), etc. According to the database accumulation of parameters and material properties, the output of the appropriate step-type orifice, mold hole distribution, reduce the pressure of the melt in the mold hole, stabilize the flow rate, to avoid clogging.

Different melt viscosities require the use of different length-to-diameter ratios (L/D), eliminating rebound, reducing shrinkage, controlling the degree of expansion, so that the particles do not drag the tail shaped, uniform and beautiful.

New Material Application 

Teflon coated die plate: adapted to special working conditions, reducing the residue of high viscosity materials. Reduces surface friction by more than 60% and extends cleaning cycles.

Pelletizing belt using tungsten carbide carbide, HV1500, to improve wear resistance and corrosion resistance, suitable for PA materials containing glass fiber, PA containing acidic materials and other working conditions.
