CNCuplum Standard Thai Rubber Process
 |
Received cuplumps are spread out in the reception area for contamination picking and DRC determination. |
 |
Big Slabs of Cup-lumps must be reduced to smaller sizes for effective removal of the contaminants and determination of the contramination levels. |
 |
Contaminants removed , cup lumps are stored according to grade and rest to obtain leveled characterisitcs |
 |
Upon designated time, cup lumps enter the STR line. Slab-cut, washed and strained to further remove embedded contaminants |
 |
Contaminants not removed during the automated processes are removed by hands. |
 |
Processed cup lumps are collected in a tank with water overflowing to remove 1. floating particles/contaminants such as raffia, woodchips, branches 2. sinking material such as dirt, sand, gravel sinks to the bottom of the tank and remove periodically. |
  |
After series of size reduction, rubber crumbs are crepe in series of decreasing thickness to obtain aggregated rubber crumbs |
 |
Crumbs are placed in trolley and oven-dried at 120?C for 7-8 minutes depending on the nature of the input cup lumps |
  |
Biscuits are baled and packed in PE pouches |
 |
Each bale passes through the metal detector to prevent any possible metal contaimination that can cause serious damage to the customer machines. |
  |
Bale are inspected and sampled for 1. white spot/contamination 2. Physical Characteristics |
 |
Baled STR blocks are packaged according to the customer specifications. |
  |
Rubber bales are tested for the physical properties and are graded as such. |
