SAN

SAN (styrene-acrylonitrile) molding is a technique suited for producing plastic components that require transparency, gloss and good chemical resistance. SAN is a thermoplastic copolymer derived from styrene and acrylonitrile, highly appreciated for its rigidity, dimensional stability and ease of processing.

Thanks to its unique properties, it is often used in the production of household items, appliance parts and technical components. Companies like Expyou harness the potential of this material to deliver tailor-made solutions that are both technically precise and aesthetically refined.

Characteristics of SAN in injection molding

SAN stands out for its natural transparency and the ability to achieve bright, smooth surfaces. It is often considered an alternative to polycarbonate or PMMA for applications that do not require high mechanical strength but where appearance and chemical resistance are key.

Main advantages of the material include:

• Excellent transparency and visual brilliance
• Good chemical resistance, especially to detergents, alcohols and oils
• Rigidity and dimensional stability, even under moderate thermal stress
• Easy coloring, with glossy or matte finishes available
• Food compatibility in some certified formulations

Available in tinted or specially finished versions, SAN is ideal for products that combine form, function and visual impact.

How does SAN molding work?

SAN molding is performed through injection: the material, in granule form, is heated to its melting point and injected into a steel or aluminum mold. After cooling, the part is ejected, inspected and, if necessary, finished or assembled.

While SAN is easy to process and ensures short cycle times, it still requires careful control of parameters to avoid internal stress or surface dullness. Expyou uses modern, computer-controlled presses to guarantee optical quality and dimensional precision, even in large-scale production.

Key advantages

SAN molding delivers components with an excellent balance between aesthetics and performance:

• Outstanding transparency, ideal for visible products, dispensers, containers and design accessories
• Glossy, smooth finish, ready for customization or printing
• Good chemical resistance, suitable for products exposed to aggressive substances
• Dimensional stability, essential for precise component fitting
• Cost-effective production, with short cycle times and high repeatability
