Pwm tej teeb meem

1. Raw edges
2. a) Confirm whether the number of frames and quab yuam quab yuamntawm txhaj tshuaj tshuab are sufficient
3. b) Paub meej tias lub siab siab dhau lawm

1) Yog hais tias tus qauv unsaturated tseem muaj burrs, nws txhais tau hais tias cov pwm clamping tsis zoo los yog qhov txhaum yog tawg.

2) If the mold clamping is not good and the size is too small when the pressure is reduced, the size problem needs to be confirmed

1. c) Poor clamping → re-closing

2. Breaking

Poor discharge positioning of male and female molds or wrong electrode size → put them in place again (need to evaluate the difficulty of mold repair, whether

(Under the influence of function and appearance, the size can be allowed to be larger)

3. Pull the male mold (deformation)

1. a) Insufficient lighting (scratches, whitening or deformation) → Strengthen lighting
2. b) Insufficient draft angle → The draft angle can be increased without affecting the function or shrinking the appearance.
3. c) Insufficient ejection, unevenness → add ejector pin or change ejection position
4. d) Poor positioning of ejector slippage → Ejection head bites to increase friction
5. e) The injection pressure is too large (especially near the inlet, the inlet position is poorly selected or the meat is too thin to obstruct the flow)

→Change the feeding position or increase the thickness of the meat to help flow (if the appearance does not shrink and does not affect the function)

4. Pull the master pwm
5. a) Mold undercut:

(1) Design error → change design

(2) Construction error→modify mold

1. b) Poor biting:

(1) Bite the flower barb → light up, heavy bite or partial bite

(2) Overbite → lighting

(3) Bite too deep and draw the flower (the thickness of the bite, the depth needs to match the draft angle) → polish, heavy bite or partial bite, change the draft angle if necessary

1. c) After biting the flower, qhov rub ntawm tus txiv neej pwm tsis txaus → tus txiv neej pwm tom lub paj los yog thawb tawm tus pin mus tom lub paj kom rub rov qab
2. Punching duab ntxoov ntxoo

1. a) Tus nqi hluav taws kub ntawm qhov nkag yog ceev heev → txo qhov hluav taws kub los yog ua kom lub inlet loj, tab sis tsis txhob ua qhov loj heev kom tua

Me me.

1. b) Lub qhov dej txias txias tsis zoo → Siv cov pwm nrog plaub qhov ua piv txwv, qhov txias slug zoo x3 thiab lub taub hau txias slug x2 yuav tsum loj txaus

6. Txoj kab fusion yog pom tseeb (painting yuav overwritten)

1. a) Cov pwm kubtsawg dhau → kho cov pwm kub (tab sis nws yuav tsum tau nyob rau hauv lub Scope ntawm tsim nyog loj ntau lawm)
2. b) Kev cuam tshuam tsis txaus → tus txiv neej qauv tom cov paj ntxhib saum toj MT11030, thiab qhov ntws tau cuam tshuam
3. c) Insufficient air escape → Strengthen escape air (add air escape blocks or injects, lwm yam., if necessary, escape air burrs)
4. The position of the fusion line causes the parts to break easily

If the fusion line cannot be eliminated

1. a) Adjust the adjustment button to control the uneven feed volume to shift the fusion line
2. b) The feed inlet is shifted

8. Broken shadow

Excessive fluctuations in the height of the public model (insufficient differentiation) cause àincrease the differentiation area (be careful of interference problems) The public model bites the rough flower and has disturbed the flow

9. The gloss is different

1. a) Check whether the mold cavity is greasy → scrub
2. b) Check whether the mold cavity is affected by the adhesion of the rubber mold caused by the high mold temperature → scrubbing
3. c) The mold temperature is wrong, the higher the temperature, the more foggy → adjust the mold temperature, adjust the temperature while shooting, and hit the color difference
4. d) Encapsulation due to poor air escape → Strengthen the escape of air near the enclosure or the flow channel

A If at the biting position:

1. a) The thickness of the bite is the same as the depth. àCompared to the old parts and samples. b) Sandblasting error→Re-spraying
2. Lighting part:
3. a) The number of polished numbers is incorrect.
4. The color difference is different
5. a) Confirm resin
6. b) Adjust the mold temperature
7. Air bubbles (transparent material)
8. a) Poor escape gas → Strengthen escape gas (flow channel, escape gas block or burrs when necessary)
9. b) The rate of fire is too fast → adjust the machine
10. c) The injection pressure is too small → adjust the machine
11. d) The inlet or runner is too small
12. e) Insufficient drying of rubber particles
13. The clamping line is obvious

1. a) Poor clamping → re-closing
2. b) Male and female mode breakage → (refer to breakage handling)

13. Poor filling:

1. a) Confirm the pwm kub and whether the material temperature is too low and affect the fluidity b) Whether the shooting speed and the shooting pressure are too low
2. c) Is the inlet flow channel appropriate (large enough, wide enough, and deep enough?) d) Is the exhaust gas sufficient?
3. e) Whether materials can be stolen (non-structural parts should be stolen as much as possible)
4. Shrink
5. a) Confirm whether the holding pressure is sufficient (if the mold burrs have occurred, the gauge pressure has been too large) b) Confirm whether the thickness of the shrinkage is too thick àStealing meat or adding materials nearby

15.Warpage

1. a) Whether the injection pressure is too large b) Whether the full pressure is too long c) The temperature difference between the male and female molds is wrong d) Whether the ejection is bad

16.Thimble Shadow

1. a) Confirm the time when the thimble shadow appears, before or after ejection?

Before ejection: The top plate of the mold is insufficiently rigid and deformed due to pressure After ejection: The meat is too thin or the ejection is too deep or too shallow
