1. Bentuk sistem pintu tidak wajar, pintu kecil, pelari kecil dan jalan aliran panjang, rintangan aliran material adalah besar, dan suhu material jatuh dengan cepat.

2. Suhu bahan atau suhu acuan terlalu rendah.

3. Plastik mempunyai ketidakstabilan yang buruk. Apabila bahan sejuk bercampur, kelajuan penyejukan cepat.

4. Terdapat kelembapan atau pelincir dalam acuan, inflasi yang berlebihan bahan cair, dan agen pelepasan yang berlebihan.

5. Tekanan suntikan terlalu rendah atau kelajuan suntikan adalah perlahan.

6. Bentuk produk adalah miskin dan ketebalan dinding tidak sekata, menyebabkan bahan cair berkumpul di kawasan berdinding nipis.

7. Sistem penyejukan yang tidak betul dari acuan atau ekzos miskin.

8. Plastik dicampur dengan bahan -bahan yang tidak dapat dilepaskan, minyak atau tidak mempunyai demolding yang betul.

1.Membuat sistem pintu, tingkatkan pintu atau pelari, mengurangkan rintangan aliran dan rintangan aliran bahan, dan mengekalkan julat suhu bahan.

2. Meningkatkan suhu gam cair silinder dan mati.

3. Bagi bahan -bahan dengan ketidakstabilan yang lemah, mencegah bahan -bahan sejuk daripada ditambah untuk mempercepatkan penyejukan dan mempengaruhi kadar aliran.

4. Periksa lubang ekzos, keringkan dinding dalaman mati, atau gunakan plastik, aditif, dan lain -lain mengikut proses dan standard teknikal.

5. Meningkatkan nilai penetapan tekanan suntikan dan kelajuan.

6. Meningkatkan bentuk produk atau meningkatkan masa kitaran pencetakan suntikan.

7. Semak sistem penyejukan dan keadaan lubang ekzos.

8. Periksa jika plastik bebas dari pencemaran, bersihkan dinding acuan, dan gunakan ejen pelepasan acuan yang sesuai untuk memecahkan produk.

1. Plastik tercemar, kurang kering atau mengandungi bahan yang tidak menentu.

2. Sebahagian besar bahan plastik dan kitar semula yang dicampur bersama menyebabkan arah yang berlebihan dari pengecutan plastik atau pengagihan pengisi yang tidak sekata.

3.

4. Improper positioning of the ejector pin or ring, or improper forming conditions, excessive stress, and poor ejection.

5. The temperature of the tool and die is too low or uneven.

6. The injection pressure is too low and the injection speed is too slow.

7. The injection time and holding pressure time Settings are too short.

8. The cooling time is not properly adjusted, either too long or too short. The cooling of the products after demolding or post-treatment is uneven, or the mold release agent is used improperly.

1.Check whether the plastic is contaminated or adulterated, etc.

2. Strictly control the proportion of plastic recycled materials and waste materials added to ensure that the plastic can be well plasticized.

3. Modify the die design to eliminate small slopes, sharp corners and notches.

4. Adjust and install the ejector pin device to ensure that the ejector pin can smoothly push out the product without any collision.

5. Adjust the temperature of the die and tool to maintain it at normal or increase it.

6. Increase the set values of the injection pressure and speed parameters.

7. Add the setting of parameters for injection time and holding pressure time.

8. According to the specific conditions of the products, adjust the cooling time reasonably and use the mold release agent properly to ensure that the cooling state of the products is uniform after demolding.

1.Uneven plasticization of plastic, excessive or insufficient feeding and filling.

2. The gate positions are improper, asymmetrical or insufficient in number.

3. The mold strength is insufficient, it is prone to deformation, the precision is not high enough or it is damaged, the positioning is unreliable or the ejection position is improper.

4. The demolding system is poorly designed or improperly installed, resulting in uneven force distribution during demolding.

5. The plastic material temperature is too low, the mold temperature is low, the injection nozzle aperture is small, and the shear stress is large when the injection pressure speed is high.

6. When the material temperature is high, the mold temperature is high, the filling effect is excessive, the holding pressure and feeding are too large, and the injection pressure is high, the residual stress is too large.

7. Uneven thickness of the product, improper parameter adjustment, uneven cooling or uneven shrinkage.

8. The cooling time parameter is set too short, causing deformation of the demolded products. The deformation of the products is not properly treated or stored.

9. Uneven mold temperature, uneven cooling, slow cooling of the thick wall parts, fast cooling of the thin wall parts, or rapid cooling of the protruding parts of the plastic part

The concave part cools down slowly.

1.Adjust the reclining position of the screw to reduce the feeding, lower the injection pressure or increase the pressure

2. Change the gate or control the flow rate at the gate.

3. Inspect or modify the mold or install and correct it to ensure accurate positioning, good precision and appropriate ejection position.

4. The design can be modified or reinstalled and debugged to ensure uniform force distribution when the product is demolded.

5. Increase the temperature of the melt cylinder and the mold, and reduce the injection pressure and speed to prevent excessive shear stress.

6. Reduce the temperature of the melt cylinder and the mold, decrease the injection pressure and hold pressure for feeding to prevent excessive residual stress.

7. Check whether the mold is heated evenly, or modify the mold to make its thickness uniform, or adjust the parameters reasonably to make the shrinkage uniform.

8. Increase the setting value of the cooling time parameter, adjust other parameters, strengthen the post-treatment process and ensure reasonable storage and stacking to avoid external factors Deformed by force.

9. Adjust the mold cooling system to control and evenly distribute the mold temperature, avoiding uneven cooling causing uneven temperature, uneven shrinkage and deformation of the plastic part.
