The problem of slipper uneven color in the production process may be caused by various factors.
The following are some of the main reasons and corresponding solutions:
1. Main reasons
Uneven distribution of colorants:
During injection molding, blowing, foaming, or dyeing processes, if the colorants are not evenly distributed, it can lead to slipper uneven color.
Batch differences in materials:
Different batches of raw materials may have color differences. If used directly without sufficient mixing or adjustment, it will affect the color consistency of the final product.
Improper production process control:
Inaccurate control of parameters such as temperature, pressure, and time during the production process, or improper material proportioning, can all lead to slipper uneven color.
Equipment performance issues:
Unstable or aging performance of dyeing equipment, injection molding equipment, etc. may also affect the uniformity of color.
2. Solution strategy
Add silicone additives:
Silicone masterbatch can help solve the problem of slipper uneven color in production. The following is the role and related analysis of silicone masterbatch in solving the problem of slipper uneven color:
Dispersion:
Silicone masterbatch contains high or ultra-high molecular weight siloxanes, which are pre dispersed in a series of polymer carriers and can be fused with almost all types of thermoplastic materials. In the production of slippers, the good dispersibility of silicone masterbatch helps to evenly distribute pigments in the plastic, thereby reducing the slipper uneven color.
Compatibility:
Silicone masterbatch has good compatibility with various plastic materials, which helps improve the bonding force between color masterbatch and slipper substrate, allowing pigments to adhere more stably to the plastic surface and reducing color unevenness caused by pigment shedding or migration.
Processing performance:
Silicone masterbatch can also improve the processing fluidity of plastics, reduce torque, minimize equipment wear, make plastics easier to fill molds during injection molding or blowing foaming, thereby reducing slipper uneven color.
Strengthen the quality control of raw materials:
Ensure that the color and quality of each batch of raw materials meet the standards.
Mix the raw materials thoroughly before use to eliminate color differences between batches.
Optimize production process:
Develop a strict production process control plan to precisely control parameters such as temperature, pressure, and time during injection molding, blowing, foaming, or dyeing processes.
Regularly maintain and calibrate production equipment to ensure its stable performance.
Improve color matching and mixing methods:
During the injection molding blowing foaming or dyeing process, add an appropriate amount of toner and ensure uniform distribution of the toner through technical means.
Using advanced color mixing equipment and technology to improve the uniformity and efficiency of color mixing.
Strengthen quality inspection:
Set up multiple quality inspection points during the production process to strictly check the color of slippers.
For slipper uneven color, rework or scrap them in a timely manner to avoid defective products entering the market.
Introduce advanced technology and equipment:
Introduce automated and intelligent production equipment and technology to improve production efficiency and product quality.
Utilize advanced detection technology and equipment to accurately measure and evaluate the color of slippers.
