How Plastic Molding Machines Improve the Quality of Plastic Toys？

Plastic Molding Machines 12-1

Plastic toys still occupy a large part of the global toy market. If these large and small plastic toy companies want to stand out, in addition to unique designs, they must also improve quality to make their products last longer. Their quality can vary greatly due to factors such as material consistency, mold design, and injection molding process. One of the most critical factors affecting overall quality is the plastic molding machine. The parameter settings of the plastic molding machine, the performance level, and other factors will affect the final toy quality. Therefore, in this guide, we will briefly introduce you to the common problems of plastic toys, the factors that cause these problems, and how Topstar’s plastic molding machines can deal with and solve these problems.

Common Problems with Plastic Toys

Common problems with plastic toys include burrs, warping, surface defects, poor color consistency, and even health hazards caused by substandard plastic materials. These problems usually occur due to outdated machines, inefficient molding processes, and poor quality control. Flash is one of the most common problems faced by plastic toy manufacturers. Flash refers to excess plastic overflowing the mold cavity, creating rough edges or excess material, which affects the appearance and safety of the toy. Warping refers to uneven cooling of the plastic, causing the toy to lose its original shape or deform. Surface defects can also make toys less visually appealing, reducing their overall market value.

What causes quality problems in plastic toys?

Quality problems in plastic toys often stem from issues in the injection molding process. Conventional plastic molding machines can be subject to various limitations. For example, inconsistent temperature control, pressure fluctuations, and poor mold design can all lead to defects in the final product. If temperature control is not precise, it can cause uneven cooling, which can cause distorted or defective toy shapes. Inconsistent pressure during an injection can cause voids or incomplete filling of the mold, creating weak points that compromise the structural integrity of the toy.

In addition, the type of material used in the molding process and the consistency of the original plastic also determine the durability and overall quality of the finished toy. Of course, old or outdated plastic molding machines may not have the latest technology required to produce high-precision molds or process modern, high-quality plastics. This leads to a need for more consistency and quality issues in the finished product.

How do plastic molding machines solve these problems?

In the face of inconsistent temperature control, Topstar’s plastic molding machines can be integrated with mold temperature controllers for equipment interconnection. Through self-developed system integration, the primary and auxiliary machines are combined, and sensor technology is used to achieve optimal temperature control. The PID temperature control algorithm used in the mold temperature controller can improve the temperature control efficiency by 10% and ensure the uniformity of the mold temperature. Accurate temperature regulation ensures uniform cooling of the plastic and reduces the occurrence of problems such as warping. In terms of pressure control, the system adopts proportional back pressure control to achieve a multi-stage back pressure setting, which increases precision and improves the plasticization quality. When facing different plastics, we use three small parts of precision PVD alloy and a standard electroplated screw to control better the temperature of the feed port, suitable for a broader range of rubber materials.

Improve safety

For manufacturers in the toy industry, the children’s toys produced must comply with strict safety regulations to ensure that they do not contain harmful chemicals, sharp edges, or small parts that may cause suffocation hazards, for some customers who have high-end production and high requirements for safety and cleanliness, electric plastic molding machines can be used for production. The “electric drive injection molding process integration” design they adopt can monitor key parameters such as temperature, pressure, and material flow in real-time to ensure that the molding process operates within a predefined safety range. The electric injection molding method is also cleaner in oil pressure, ensuring that the molded toys are pollution-free and healthier for children.
