First, with large materials process:
1. Abnormal raw materials:
Main cases: agglomeration of raw materials, mildew and impurities.
Result: Product quality issues.
2, the school pound:
Main case: There is a large error in weighing with electronic pounds and it is not corrected.
Result: The weighing error of the raw materials causes the ingredients to be wrong. In the re-named segment, the workflow is interrupted, which affects production efficiency and progress.
3, check the formula:
Main case: Unchecked formula, using the wrong formula.
Resulting in the result: mismatched materials, the work process is interrupted in the re-named section, thus affecting production efficiency and progress.
4, on-site cleaning after the ingredients:
Main situation: The ingredients were not cleaned, causing cross-contamination of raw materials.
Result in: waste of raw materials or quality problems.
5, the amount of raw materials after the ingredients:
The main situation: the code is chaotic, can not distinguish the batch.
Resulting in the result: it is difficult to increase the pushing work, it is easy to push the wrong material, and the work process is interrupted in the re-named part, thus affecting the production efficiency and progress.
Second, with small materials process:
1. Checking formula:
The main situation: did not pay attention to the amount of use indicated in the formula, the ingredients have made mistakes.
Result: Mismatched small materials, the work process is interrupted in the re-named part, which affects production efficiency and progress.
2, according to the order ingredients:
The main situation: not in order, the ingredients are placed on the scene.
Result: Resulting in repeated batching of small ingredients, more matching. In the re-named segment, the workflow is interrupted, which affects production efficiency and progress.
3, raw material anomalies:
Main case: The date of production of the small material was not checked, and the raw material agglomerated and the main components failed.
Result: Product quality issues.
4, the school pound:
Main case: There is an error in the weighing of the electronic pounds and it is not corrected.
Result: Small material weighing error, resulting in ingredient errors. In the re-named segment, the workflow is interrupted, which affects production efficiency and progress.
Third, push materials, over-repeated process:
1. Check the batch of varieties:
Main case: The varieties and batches of large raw material varieties and batches and small materials were not checked.
Causes the result: causing a missed push or pushing the wrong material. In the re-named segment, the workflow is interrupted, which affects production efficiency and progress.
2, the school pound:
Main case: There is an error in the weighing of the electronic pounds and it is not corrected.
Result: Small material weighing error, resulting in complex weighing error. product quality problem.
3, leakage:
The main situation: due to the breaking of raw materials, not found in time or found to forget to fill.
Result: The workflow is interrupted in the re-named phase, which affects production efficiency and progress.
4, check the small material package and large material fraction:
Main case: It is not checked whether the large material fraction and the small material package of the pushed batch are consistent with the process card.
Result: The wrong material or small material package, or forget to push, production error, resulting in machine failure, work process interruption, thus affecting production efficiency and progress. If not found in time, it will directly affect the quality of the product.
5, check the interval between the two batches of raw materials:
The main situation: push the two batches of raw materials without obvious spacing, and place them at will.
Resulting in the result: incorrect feeding during production, or affecting the efficiency of the feeder, causing the work flow to be interrupted, or even causing the return, thus affecting production efficiency and progress.
Fourth, feeding and mixing process:
1. Check the batch of varieties:
Main case: Unchecked batches and screened.
Result: Production produces errors, or the finished product produces agglomeration, causing product quality problems.
2. Thoroughly clean the feeding port and the feeding port:
Main case: The feed port was not cleaned or cleaned after each batch was finished.
Result: Lead to cross-contamination of raw materials, causing product quality problems.
3. Feeding according to the order of feeding:
Main case: The feeding was not carried out at random according to the order of feeding specified by the technical department.
Result: The mixing of the mixer is uneven, causing product quality problems.
4, the mixer operates correctly:
The main situation: no first open the mixer, after the feed; and first feed, then start mixing.
Result: Damage to the mixer or even mixing, causing product quality problems.
5, check the valve usage:
Main case: The valve is not inspected, the valve is faulty, and it cannot be closed normally. Or forget to close the valve for production mixing.
Result: Resulting in mixing, causing back-up or product quality problems.
6, the correct grasp of mixing time:
Main case: Change the mixing time or wrong timing for the purpose of improving production efficiency without the permission of the Quality Control Department. The timing should be started after the last pack of small materials has been thrown.
Causes the result: uneven mixing or grading, causing product quality problems.
7. Processing of residual materials and recycled materials:
The main situation: the remaining materials and the returned materials are not processed according to the technical department's treatment plan, holding an indifferent attitude.
Causing results: causing multiple returns, causing product quality problems.
V. Receiving and packing process:
1. Check the variety:
Main situation: It is not checked whether the packaged varieties are consistent with the production varieties, and they are blindly packaged.
Result: the wrong type of the product, resulting in production errors.
2, check the appearance of the finished product:
Main case: The appearance of the finished material is not checked for abnormality, the finished product is agglomerated, not uniformly mixed and foreign matter impurities are present.
Causes the result: causing product quality problems.
3, the school pound:
The main situation: the weighing of the electronic pounds is not corrected and produces an error.
Causes the result: causing product quality problems.
4, the position of the code:
The main situation: the finished product code is messed up, the dust is not cleaned, and the variety cannot be seen.
Result: The use of premix in production is wrong, causing product quality problems.
Sixth, the finished product receiving process:
1. Check the variety:
Main situation: It is not checked whether the delivered varieties are consistent with the production varieties, and blind feeding.
Result: The product is sent incorrectly, causing a quality accident.
2, check the appearance of the finished product:
Main case: The appearance of the finished material is not checked for abnormality, the finished product is agglomerated, not uniformly mixed and foreign matter impurities are present.
Causes the result: causing product quality problems.
3. whether the finished product warehouse and the material truck are empty:
Main case: The finished product was not finished, and the material truck was not completely discharged.
Result: Causes cross-contamination of the product, causing product quality problems.
