PS Injection Molding

The PS injection molding technology we use has distinctive features. Polystyrene (PS) material has extremely high transparency, and the molded product is crystal clear and has outstanding visual effect, which is often used in the manufacture of products with high requirements for appearance. Its excellent flow allows it to easily fill complex mold cavities during the injection molding process, allowing us to efficiently produce parts with a wide variety of shapes and delicate structures. PS material has high hardness, and the surface of the product made is smooth and flat, with good wear resistance and certain rigidity. However, PS materials have relatively low toughness, and we design our products with this characteristic in mind, balancing the performance of our products by optimizing the structure or selecting the right modified materials. In addition, the PS injection molding process is simple and the molding cycle is short, which can meet the needs of high-volume production and provide strong support for reducing production costs.

PS Injection Molding Material Selection: Precise Adaptation of Multiple Properties

In terms of material selection, we will precisely select the right PS material according to the specific needs of the product. General-purpose PS has good optical properties and processing properties, and is often used in the manufacture of stationery, toys, photo frames and other daily necessities with high appearance requirements. High Impact PS (HIPS) is modified by adding rubber to significantly improve toughness and impact resistance, and is suitable for manufacturing products that need to withstand certain external forces, such as home appliance shells and instrument shells. Flame retardant PS has been specially treated with good fire performance, and is widely used in electronic and electrical products to ensure the safe operation of equipment. In addition, there are some special-purpose PS materials, such as foamed PS (EPS), which have the characteristics of light weight, heat insulation, and good cushioning performance, and are often used in the field of packaging materials and building insulation; Expandable PS (EPS beads) can be foamed to form foam with good cushioning properties, which plays an important role in express packaging, protection of fragile items, etc.

PS Injection Molding Production Process: Standardized and orderly manufacturing process

Our PS injection molding production process follows strict regulatory standards. First of all, according to the product design requirements, the professional design software is used to design the mold to ensure that the mold structure is reasonable and the size is accurate, and then the mold is manufactured through high-precision processing equipment to lay the foundation for product molding. Subsequently, the PS raw material is pre-treated, and although the PS material has low moisture absorption, in order to ensure product quality, we still dry it appropriately to remove the trace moisture that may be present and prevent defects such as bubbles and silver wires during the molding process. Then enter the injection molding process, the dried PS raw material is fed into the barrel of the injection molding machine, heated to a molten state, and quickly injected into the mold cavity under high pressure, and the product is fully filled after pressure holding, and then quickly cooled and shaped through the cooling system. Finally, the post-processing process includes the removal of gates, burrs, necessary trimming and quality inspection of the product to ensure that each product meets the quality standards.

PS Injection Molding: A wide range of options for aesthetic optimisation

We have mastered the surface treatment technology of a wide range of PS injection molded products to meet different appearance and functional needs. In order to improve the surface gloss of the product, we often use polishing treatment, through mechanical polishing or chemical polishing, so that the surface of the product can achieve a mirror effect and enhance the visual beauty. The spraying process is one of the methods we commonly use, which can spray a variety of colors and textures of paint for the product according to the design requirements, which not only beautifies the appearance of the product, but also improves its wear resistance and weather resistance. Screen printing and hot stamping technology can add text, patterns and logos to the surface of the product, giving the product a unique brand image and personality. In addition, for some products with special needs, we will also use electroplating treatment to make the surface of the product show a metallic luster and improve the product grade; Or frosted treatment to increase the texture and friction of the product surface to meet the needs of different use scenarios.

PS Injection Molding Dimensional Inspection: Strict and meticulous quality control system

In terms of dimensional inspection, we have established a strict and meticulous quality control system. We will first use basic measurement tools such as calipers and micrometers to make preliminary measurements of the key dimensions of the product, and quickly screen out products that obviously do not meet the requirements. For products with high precision requirements, we use the CMM for accurate measurement, which can detect the product in three dimensions in an all-round way, accurately obtain the size deviation of the product, geometric tolerance and other data, and ensure that the product size meets the design requirements. At the same time, we will also use optical inspection equipment to quickly detect and compare the appearance and size of products through image recognition technology, and find small size differences and defects in time. Through the comprehensive use of a variety of testing methods, we strictly control the quality of products to ensure that each product can achieve high standards of dimensional accuracy.

PS Injection Molding product applications: a wide range of applications covering a wide range of fields

PS injection molded products are used in a wide range of applications in our lives and production. In the home sector, PS is often used in the manufacture of photo frames, decorative ornaments, storage boxes, etc., and its high transparency and beautiful appearance add color to the home environment. In the toy industry, PS material is widely used in the manufacture of various toys due to its good processing performance and rich color performance, to meet the diverse needs of children for toys. In the field of electrical and electronics, high-impact PS and flame-retardant PS are used in the manufacture of TV housings, computer cases, keyboards and other components to ensure the safety and durability of equipment. In the field of packaging, foamed PS and expandable PS foam plastics have become ideal packaging materials for fragile items such as electronics, glass products, and ceramics due to their light weight and good cushioning properties. In addition, PS injection molded products can also be found in stationery, medical equipment, automotive interiors and other industries, and their excellent performance and diverse characteristics make them indispensable manufacturing materials for many industries.
