Corrugated pipe forming machine fault condition analysis

Corrugated pipe forming machine, metal hose machine will appear a lot of use man-made fault, the following content, double jia lists nine for everyone very common fault of the user, analyzed the cause of such failure may occur, you can serve as a reference.

A. Corrugated pipe forming machine lack of glue

(1) pipe and material mouth temperature is too low.

(2) the mold temperature is not enough.

(3) the machine add feed rate was not enough.

(4) the injection pressure is too small.

(5) injection speed is too slow.

(6) injection time is too short.

2. Burrs

(1) the injection pressure is too large.

(2) the mold temperature is too high.

(3) the mold a foreign body inside.

(4) don't die closed tight, clamping pressure is not enough.

(5) the mould damage.

3. Corrugated pipe forming machine

(1) molding machine high temperature, injection speed is too slow.

(2) forming internal model have glue phenomenon.

3) die, outside is too thick, natural product volume contraction.

(4) the pressure is too low.

4. Corrugated pipe forming machine deformation

(1) forming machine cooling time is not enough.

(2) the mold temperature is too high.

(3) the molding products inside and outside thickness difference is too big.

(4) homework take take action is not standard.

5. Water lines

(1) rubber temperature is too high.

(2) raw material containing water, not completely dry.

(3) the injection pressure is not enough.

(4) mould inlet is too small.

6. Corrugated pipe forming machine of bubbles

(1) rubber contains water.

(2) rubber temperature is too high, or in the feed tube and cavity within the heating time is too long.

(3) the injection pressure is too great.

(4) the air material tube.

7. The joint line

(1) rubber temperature is too low.

(2) mold design feed point too much.

(3) the injection speed is too slow.

(4) injection mold release too much.

(5) the mold venting is not good.

Eight. Corrugated pipe forming machine crescent

(1) forming a pressure is too large.

(2) the temperature is too high

(3) the mold venting is not good

Burned in nine.

(1) the machine temperature is too high.

(2) material is raw materials.

(3) the molding time is too long.
