Suction Blow Molding Service | Complex Hollow Plastic Part Manufacturing
Intro Paragraph:
Suction Blow Molding is an advanced hollow plastic forming process that combines vacuum assistance with traditional blow molding technology. By using vacuum pressure during forming, the molten plastic can better conform to complex mold geometries, improving dimensional accuracy and surface consistency. As an experienced plastic parts manufacturer, we provide reliable custom suction blow molding solutions for automotive ducts, industrial tubing, and irregular hollow plastic components. Whether you need non-standard plastic molding or small-batch plastic parts customization, we offer precision manufacturing, stable quality, and efficient production support.
Molten plastic is extruded into a hollow tube-shaped parison with controlled wall thickness.
The mold closes around the parison while vacuum pressure helps the material conform tightly to complex mold surfaces.
Compressed air expands the plastic material fully against the mold cavity, ensuring accurate hollow part formation.
Controlled cooling maintains dimensional stability and reduces shrinkage or deformation.
Finished parts undergo dimensional inspection, leak testing, trimming, and surface quality checks before delivery.
| Material | Key Benefits | Typical Applications |
|---|---|---|
| HDPE | Chemical resistance, durability | Industrial ducts |
| PP | Lightweight and heat resistant | Automotive air channels |
| PVC | Rigidity and smooth finish | Industrial tubing |
| ABS | Impact resistance | Technical hollow components |
| PA (Nylon) | High strength and wear resistance | Automotive systems |
