| Condition | Description | Reasons | Solution |
| 1 | if there are too many small holes in the surface it will be difficult to release the fiberglass molding products. | The feeding area is too large, and the surface air is not discharged due to the short process | Reduce the feeding area and add small material sheet at the top of the large sheet. |
| 2 | The clipping edges are too large. | Repair clipping edges. | |
| 3 | There is dry fiber.The initial viscosity of the resin paste is too high. The glass fiber is not fully saturated. | Reduce the initial viscosity of the resin paste, increase the work roll in the impregnation area, and replace the glass fiber. | |
| 4 | Pre-gelled area on the fiberglass molding part | Reduce mold temperature and add inhibitor to resin paste. | |
| 5 | SMC material dry | When using the anti-seepage film to wrap the SMC material, the quantity of zinc stearate can not be prepared too much. | |
| 6 | Fiberglass SMC material too soft. | Increase thickening time or increase thickening temperature to increase thickening viscosity level. | |
| 7 | Insufficient pressure | Increase molding pressure |
