Injection Molding Defects and Solutions -- Whitening 2025-10-20

Whitening (Stress Whitening): During demolding, excessive ejection force is applied to the surface areas around ejector pins or grooves. Due to forced demolding, high internal stress develops in these regions, sometimes causing deformation. Whitening is a sign of stress cracking. Materials such as ABS and HIPS are particularly prone to this phenomenon.

Injection Molding Defects and Solutions -- Stains 2025-10-20

Stains, Impurities, and Foreign Substances The plastic material is impure or contaminated. 23.1 Causes 23.2 Solutions 23.1.1 Raw materials, pellets, or pigments are impure. 23.2.1 Replace the raw materials, dyes, or pigments. 23.1.2 The plastic has decomposed or deteriorated. 23.2.2 Adjust the processing conditions to prevent material decomposition. 23.1.3 The barrel and hopper are not clean. 23.2...

Injection Molding Defects and Solutions -- Poor Transparency 2025-10-20

Poor Transparency: Due to poor contact between the molten material and the mold surface, tiny pits appear on the surface of the molded part, causing light scattering. Alternatively, the mold surface may not be sufficiently polished, resulting in decreased or uneven transparency in transparent products. 22.1 Causes 22.2 Solutions 22.1.1 Low mold temperature or low material temperature, causing poor...

Injection Molding Defects and Solutions -- Dull Surface 2025-10-20

Dull Surface (Lack of Gloss): Due to poor mold surface finish, inadequate contact between the molten material and the mold surface, or improper material and mold temperatures, the molded product fails to exhibit the natural gloss of the resin. Instead, the surface appears whitish, cloudy, or dull. 21.1 Causes 21.2 Solutions 21.1.1 Poor mold surface finish; presence of scratches, moisture, or oil c...

Injection Molding Defects and Solutions -- Unmelted Lumps 2025-10-20

Cold Slugs / Unmelted Lumps: Unmelted or insufficiently plasticized material enters the mold cavity along with the melt flow, causing hard plastic lumps to become embedded inside or on the surface of the molded part. 20.1 Causes 20.2 Solutions 20.1.1 Material temperature, mold temperature, and nozzle temperature are too low, or injection speed is too slow. 20.2.1 Properly increase the material, mo...

Injection Molding Defects and Solutions -- Gate Sticking 2025-10-20

Gate Sticking: The gate sticks in the gate sleeve due to mechanical resistance inside the sleeve, insufficient cooling, or a malfunction of the pull pin. 19.1 Causes 19.2 Solutions 19.1.1 Insufficient runner draft angle, no mold release agent used. 19.2.1 Increase the runner draft angle and apply mold release agent appropriately. 19.1.2 Cooling time too short, nozzle and fixed mold temperatures to...
