Degating and Cutting Solutions


The SAS complete line of pneumatic cutters and degating systems includes knives, nippers, blades, sprue cutters, and CNC degaters for any plastics application. Handheld and automatic cutters are available.

With the widest variety of lightweight cutting tools, you can easily select the tool that best meets your production challenges. Cutting blades can be easily rotated for left or right-handed operation, and all units are easily maintained. Many styles and sizes of blades are available to suit your application..

Work Knife

SAS Work Finisher is a safe, ceramic knife that deburs hard plastics effortlessly without fear of cutting hands/fingers. It is ideal for curved and complicated shapes.

Hand-held Pneumatic Cutter

The MR Sprue Cutters with H in the part number are hand held cutters. The SAS Nip It! line of sprue cutters are hand operated, feature safety levers, and can be fixture mounted. This line features many standard and special blades. See Nip-It! section for Type-I blade information.

Static Knife Cutter

Whether mounted to an articulating robot, statically, or directly to your End-of-Arm Tool, this economical and lightweight precision cutting tool provides accurate, low cost cutting for a multitude of fan degating applications. The SAS Static Cutter includes a standard box cutter knife, protected by a safety guard, attached to an adjustable SAS elbow arm. The knife blade can easily be replaced by a simple turn of a locking handle.

Fan Gate Trimmer

This Fan Gate Trimmer cuts longer and harder to cut fan / edge gates with +/- 0.4 mm vestige tolerance. The parts are held firmly in place by a custom designed part nest made to contour the part and hold it securely. The custom blade assemblies are also uniquely designed to contour the part/ gate interface.

Lift Degater

SAS Lift Degater was designed for large plastics parts. A robot transports the part to the Lift Degater and sets the part into the “part conforming nests”, located at the top of the degater. The part is then trimmed by several precisely positioned cutting tools that match the nests. Precision and speed are coupled with several simultaneous cutting actions. The waste trim is then dropped into a container and the finished product is lowered on to the lift table. Then, the product can be removed by a packer, who is protected from the lift by a safety light curtain.

Robot Beam Mounted Degaters (rotation option)

The SAS adjustable Rotational Degater can be set as desired for dual service applications around 360 degrees. This application is especially suited for cutting multiple gates on different plastic surfaces, rotating both quickly and accurately around a part. This degater can be mounted on any robot beam. For both ease of use and fast changeovers, it can also be mounted on a quick change chuck with one-touch air fittings and be fitted with a variety of pneumatic degating tools, including a MR-50A capable of cutting plastic up to ½ inch (12 mm) in diameter.

Custom Degaters

SAS engineers use 2D and 3D CAD tools to create custom equipment that will perform operations quickly and safely. Every station is designed to increase productivity, ensure the safety of the operator, and reduce operator fatigue. SAS has tremendous experience developing special degating systems for very large as well as small and delicate parts.

EOAT mounted cutters

Get more out of your EOAT by adding the degating function to your custom tool. The SAS engineers can analyze your operation to determine the most cost efficient degating method for your part.

Rail Degaters

Compact, modular degating system for fan gates that greatly reduces finishing labor costs and provides a consistent clean cut for fan gates. Mounted on a rigid frame, this degating unit can be designed to trim either straight or curved fan gates. Radiuses as small as one inch (25.4 mm) can be cleanly degated by this system.

Punch Press Degater

Punch presses are used when the cutting vestige requirements are critical and range between 0.003 and 0.010 in. The SAS Punch Press can be operated manually or automatically and can be integrated to the robot or press. Punch press degaters uniquely provide a preferred ‘flush’ cut.

Thrust Cutter

This thrust cutter is designed with a razor sharp blade positioned at a 45 degree angle to precisely shear a sprue gate in narrow places. This cutter holds the blade on a special cylinder to precisely actuate the gate cutting process. The cylinder can be mounted in many angles. This style of gate cutting uniquely allows access to very hard to reach areas.
