Common problems and solutions of mould production

1, unreasonable design drawings

        Solution：Use graphics software to simulate the unreasonable design structure, or re design drawings, and ultimately through the audit of the drawings can be given to the workshop.

2,Die CNC processing size is too large or the wrong position
        Solution：Large position does not affect the product appearance, function, mold life, etc., can be done to replace or repair the repair, and check the cause of the error, confirm the processing program OK, re CNC processing, such as the size of the impact of the product appearance, function, mold life and so on, so that we must replace the material, check the cause of the error, confirm the processing program OK, then re CNC processing.

3,Die CNC processing size is too small or processing is not in place
        Solution：Check the cause of the error, confirm the processing program OK, and then re CNC processing.

4,EDM processing error
　　Solution：The size of processing is not enough to check the re processing; processing error in the product appearance, function, mold life, etc., can be made to replace or repair, and check the cause of the error, and then re processing program OK, such as the size of the impact of product appearance, function, mold life and so on, so that we must replace the material, check the cause of the error, confirm the processing program OK.

5, line cutting processing error
        Solution：The size of processing is not enough to check the re processing; processing error in the product appearance, function, mold life, etc., can be made to replace or repair, and check the cause of the error, and then re processing program OK, such as the size of the impact of product appearance, function, mold life and so on, so that we must replace the material, check the cause of the error, confirm the processing program OK.

6, mold flash in production
        Solution：Injection if pressure is too large, too plump product, if it is a problem of injection pressure can solve the problem by adjusting the machine. If there is a problem with the mold, check whether the mold with good or size less than the number of the re allocation mode, the local position flash can insert replacement, or welding correction.

7, the mold in the production has shrunk
       Solution：View the product design is reasonable, too thick or thickness varies too much plastic bits and adjusting machine whether can solve, mold the glue inlet is too small, mold venting is reasonable.

8, the mold in the production of the product is white, or white
       Solution：1) mold polishing, especially the bones and muscles, which can reduce product ejection resistance; 2) Thimble Made reticulate adding the ejecting force area; 3) the thimble, and do short 0.1-0.3mm increasing the thickness of the plastic bits; 4) try to mold inserts the angle made small fillet, reduce product a mode of resistance.

9, the mold in the production of the product exhaust
       Solution：May exhaust exhaust position in a predetermined, can according to the position required additional exhaust machine, cylinder exhaust bad can be below the column do thimble or do exhaust needle exhaust, bones exhaust bad can be made into insert venting or exhaust needle for the exhaust is not a good position.
