small shot size plastic processing machine

 

When small shot sizes are used with large screw diameters, the plastic material spends more time being heated by the barrel heaters compared to large shot sizes. Material degradation is more likely to occur if the shot size is small compared to the injections units maximum shot capacity especially for heat sensitive materials.

Smaller shot sizes produce greater irregularities and loss of precision, whereas larger shot sizes do not allow sufficient melt cushion for packing and for inefficiencies in plastication. You will be using a micro injection molding machine with a 3-g shot size, but the Department of Plastics Engineering has machines with shot sizes of 3-g to 8 oz.

Shot Size Too Small For Molding Machine. Explanation: If the shot size is less than 25% of the injection units maximum shot capacity then it will be difficult to maintain a stable process.An injection screw needs a reasonable distance to move to be able to maintain control over speeds and pressures.

Jan 23, 2018 · Inconsistent shot sizes: If your machine isn’t holding a consistent cushion, the shot amount for each part will be inconsistent, as greater or lesser amounts of material will be injected into the cavity on each shot. While parts may still be acceptably produced, inconsistent shot size can snowball into larger issues with machine setup.

Laser Generating Gas. Laser generating gas is different from cutting gas. Laser generating gas composition: N 2: The energy generated by the RF generator first excites N 2, causing it to be in a transition state.. CO 2: N 2 in the transition state will excite C0 2 which causes CO 2 to transition, and releases the laser.. He: Absorb CO 2 and excess energy, cool the system and turn it into heat.
