blow molding:
Blow molding is a specialized manufacturing process used to create hollow plastic parts. It involves melting plastic and forming it into a parison or preform. The parison is then inflated with air inside a mold cavity to achieve the final product shape. Sentis is renowned for its advanced blow molding machines tailored to diverse industrial applications.
Injection molding is a pivotal manufacturing technique where molten plastic is injected into a mold cavity. The plastic solidifies to form the desired shape. This method excels in producing solid plastic components with high precision and consistency.
Key Differences Between Blow Molding And Injection Molding
Applications:
Blow Molding Applications:
Blow molding is ideal for creating hollow items such as bottles, containers, and large tanks. Sentis's blow molding machines support a wide range of plastic materials, catering to industries including packaging, automotive, and industrial sectors.
Injection Molding Applications:
Injection molding is preferred for intricate designs requiring precise tolerances. Applications span automotive components, consumer goods, and medical devices, leveraging the method's precision for complex parts.
