ABS vacuum formed shell

ABS vacuum formed shell is a type of shell product made of ABS plastic through vacuum forming process, which has the following characteristics and advantages:

Material characteristics:

Good strength and toughness: ABS plastic has high strength, can withstand certain external impact and compression, is not easy to break or be damaged, and also has good toughness. When subjected to external forces, it can undergo a certain degree of deformation without easily breaking, which makes ABS vacuum formed outer shell provide effective protection for internal products or components. For example, in the fields of electronic products, instruments and equipment, it can resist collisions and falls in daily use very well.

Excellent processing performance: ABS plastic is easy to process and can be easily made into various complex shapes and sizes of shells through vacuum forming technology, meeting the design needs of different products. Whether it is a simple geometric shape or a shell with complex structures such as curves and radians, it can be easily achieved through vacuum forming technology, and the processing efficiency is high, which is conducive to large-scale production.

Good surface quality: After ABS material is vacuum formed, the surface of the shell is smooth and flat, with good glossiness and beautiful appearance. Various surface treatments can be carried out according to needs, such as spraying, screen printing, etc., to further enhance the appearance and decorative effect of the product and meet the requirements of different customers for product appearance.

Stable chemical properties: ABS plastic has good chemical stability and has a certain tolerance to general chemicals such as acids, alkalis, and salts, making it less susceptible to chemical corrosion. This allows ABS vacuum formed shells to maintain good performance and appearance even in harsh environmental conditions (such as industrial environments with certain chemicals), extending the product's service life.

Application areas:

Automotive industry: commonly used for automotive interior parts, such as dashboard shells, center console shells, door interior panels, etc; It can also be used for external components of automobiles, such as bumper shells, spoilers, etc. The strength and toughness of ABS vacuum formed shell can meet various requirements of automobiles during driving. At the same time, its good processing performance and surface quality can achieve aesthetic design and comfortable touch of automobile interiors, and it has a certain degree of weather resistance, which can adapt to changes in the external environment of automobiles.

Electronic and electrical industry: widely used in various electronic and electrical products such as TV housings, computer monitor housings, printer housings, audio housings, etc. ABS vacuum formed shell can provide good insulation protection for electronic and electrical products, prevent internal circuits from being affected by external environment, ensure the normal operation and safe use of products, and its appearance design is flexible, which can meet the external needs of electronic and electrical products that are constantly updated.

Medical device industry: can be used to manufacture casings for medical equipment, such as medical instrument casings, bed components, surgical instrument boxes, etc. Due to its good chemical stability and biocompatibility (in compliance with relevant standards), ABS plastic will not contaminate or have adverse effects on drugs, reagents, etc. that come into contact with medical devices. At the same time, it can be easily cleaned and disinfected, meeting the strict requirements of the medical device industry for hygiene and safety.

Aerospace field: It is also applied in the interior parts and some components of aircraft and spacecraft, such as aircraft seat backrests, luggage compartment interior panels, etc. Although the aerospace industry has extremely high requirements for materials, ABS vacuum formed shells can play a role in some non critical structural components and interior parts due to their excellent performance. Their lightweight characteristics help reduce the overall weight of aircraft, improve fuel efficiency or flight performance.

Other fields: In toy manufacturing, ABS vacuum formed shells can be used to make various toy shells or components, such as toy car shells, building block shells, etc., which not only ensure the safety and durability of toys, but also achieve rich and diverse styling designs, attracting children's love; In the field of display props, they can be used to make the outer shell of display racks and display cabinets. By utilizing their good surface quality and processing performance, they can create beautiful and unique display effects that attract consumers' attention.

Production process:

Mold making: Design and make molds according to the shape and size of the required ABS blister shell. Molds are usually made of materials such as steel or aluminum alloy, with high precision and strength to ensure the forming accuracy of the shell during the vacuum forming process. The design and manufacturing quality of molds directly affect the quality and production efficiency of the final product.

Board preparation: Select ABS plastic sheets of appropriate specifications and thickness. The quality and performance of the board should comply with relevant standards and requirements, and pre-treatment such as cleaning, drying, etc. is required to ensure good adhesion and forming effect between the board and the mold.

Heating softening: Place the ABS plastic sheet in a heating device for heating to reach the softening temperature. The heating temperature and time need to be precisely controlled according to the thickness, material, and requirements of the vacuum formed product of the sheet, to ensure that the sheet can be uniformly softened and reach a suitable forming state.

Vacuum adsorption molding: The softened ABS plastic sheet is quickly covered on the mold, and the air between the mold and the sheet is extracted by a vacuum pump, so that the sheet is tightly adhered to the surface of the mold under atmospheric pressure, and molded into an ABS vacuum formed shell according to the shape of the mold. During the adsorption molding process, it is necessary to control the vacuum degree and adsorption time to ensure the molding quality and dimensional accuracy of the shell.

Cooling and shaping: After the ABS plastic sheet is adsorbed onto the mold and formed, it needs to be cooled to solidify and shape it, maintaining its formed shape. Cooling methods usually include air cooling and water cooling, etc. The cooling speed and time need to be adjusted reasonably according to the size, thickness, and material characteristics of the product to prevent defects such as deformation and cracking of the shell due to uneven cooling.

Demolding and post-processing: After the ABS vacuum formed shell cools and solidifies, it is demolded from the mold and removed. Then necessary post-processing steps are carried out, such as removing burrs, trimming edges, checking quality, etc. For some products with special requirements, further processing such as drilling, cutting, assembly, etc. may be necessary to meet the final usage needs.
