Knowledge of injection molding production of raw materials mixed Introduction

 One. Purpose: To standardize mixing operation, stable production conditions.

II. Scope: Department of mixture for injection molding operations personnel.

III. Responsibilities: by the production of single, single-ingredient batching and mixing process requirements to ensure uniform mixing of the material, free of impurities and other miscellaneous materials, and timely supply of production materials.

IV. Process:

V. Job Control:

a. Attention to safety, before starting the check equipment status, timers, etc. are normal. Equipment failure, should be immediately shut down, or do not have to turn off the power supply when work; white mineral oil and other natural products must be closed easily separated;

b. Each of a different material, color mixer shall clean inside and outside, cleaning the surface first with cotton dust, toner cleaning up, then stick with a white cotton white oil scrub, then wipe clean white cotton cloth.

c. Ingredients, must check the ingredients list, identification with the physical, if consistent, can be mixing, can not arbitrarily change a single ingredient;

d. Pounds of material to be added or quantitative diffusion oil, white mineral oil, proliferation of powder must be measured accurately;

e. Note that raw materials, toner, outlet material, mixing in the spread of agents to join the order and time. Usually the order of mixing

And time:

Its order of time (mixing) the total time

①. Raw material + agent (diffusion oil) 2 minutes

②. Powder (toner, spread flour) 4 minutes 6-8 minutes

③. Plus pellet (feed intake, etc.) 1.5 minutes
