UBE Machinery's "Screws"

“UBE Machinery's Screws" that meet diverse needs with our experience and technology.

We offer a wide variety of screw variations developed by combining the experience and technology accumulated by UBE Machinery over many years. We have also inherited the technology cultivated in our 60-year history of screw manufacturing at our Nagoya Plant, which enables integrated in-house production using machining, surface treatment, thermal spraying, and screw-specific equipment to manufacture the largest and highest-quality screws.

UBE Machinery's Various Screw

UBE Machinery has the facilities for integrated in-house production of screws, the most important component of injection molding machines, which greatly affects the quality of molded products. We offer a wide variety of high-quality screws.

Variety of screws designed for different applications

UB screw(for multi-purpose)

“UB Screw” (Ultra Barrier Screw), the optimal design for customer's multi-purpose applications. Unique double flight design realizes overwhelming plasticizing capacity.

Contributions to our Customers

• Supports a wide range of molding from general-purpose plastics to engineering plastics.
• High plasticizing capacity" contributes to high-cycle molding.
• Homogeneous melting" achieves high molding quality.

Application Examples

• Automobile parts

  Bumper, Instrument panel, Headlamp lense, etc.

• Home appliances/OA parts

  PC, LCD TV, etc.

• Industrial Material parts

  Pallet, Container, etc.

• Our unique screw design, including long barrier and unmelt-less dam shape, high mixing and plasticizing capacity, and energy saving, produce excellent plasticizing performance.
• Unmelt-less plasticization contributes to lower raw material costs, such as high-magnification master batch molding and greater freedom in colorant selection.

SP III Screw(for PP high-cycle molding)

Contribution to Customers

• “PP-oriented high plasticization capability” contributes to high-cycle molding.
• “High master batch compatibility” with high dispersion mixing elements contributes to lower material costs.

Application Examples

• Automobile parts

  Bumper, Instrument panel,　etc.

• Industrial Material parts

  Container, etc.

MF-UB screw(for super-high color mixing)

Contribution to Customers

• “Adaptation to high-magnification master batches (200x or more)” contributes to material cost reductions.
• “Quick color change” contributes to rationalization of production.
• “No need for mixing nozzles” realizes lower equipment costs and effective use of injection pressure.

Application Examples

• Automobile parts

  Bumper, Instrument panel, Trim parts, etc.

MD-UB screw(for super-high mixing)

Contribution to Customers

• “Homogeneous mixing” realizes high-cycle molding of PP

Application Examples

• Automobile parts

  Bumper, Instrument panel, Trim parts, etc.

LFT screw(for Long Fiber Thermoplastics)

Contribution to Customers

• Molding of high-rigidity and high-strength parts realized by “function to suppress cutting of reinforcing fibers”.
• Contribution to “weight reduction of automobiles”.

Application Examples

• Automobile parts

  Module parts, etc. (front end, door)

F screw(for low shear, low heat generating)

Contribution to Customers

• Contributing to the molding of transparent parts and optical parts with “high transparency and contamination-free melt quality”.

Application Examples

• Transparent parts

  Light guide plate, glazing, lens, etc.
