Selecting the Correct Gate Cutter for Your Application:

To ensure a quality finished product, it is important to choose the proper gate cutter. Consider the following when selecting a cutter:

  1. Contour of the back of the blade
  2. Blade length
  3. Blade opening
  4. Handle length
The blade characteristics should match the part at the area of de-gating.

Why Cutters Matter

Gate cutters are essential hand tools for injection molders for trimming molded parts free from the gate.

A clean and aesthetically pleasing plastic part relies on a cutter that can provide and consistent and precise cut flush to the molded part and cut cleanly in order to remove the part without damage.

This performance  cut must be achieved for every part and over a long period of time.

Because every cut requires the skill and dedication of the operator, the feel and ease of the cut is critical. Right or left handed, the cutter needs to be comfortable and easy for the operator to use for an extended amount of time. All of our cutters offer precision cutting and a user-friendly design.  Our handle are ergonomically shaped to fit most hand sizes.  The grips are made from a  durable, non-slip material. A  built-in high quality return spring brings the tool back to the open position again assisting the cutting process.


Our Technology


Our products have been in the hands of our customers for decades and we have relied on their feedback to continually update and advance our products so that today we  offer the best possible available on the market

Steel Quality Matters

The first step in the manufacture of a high performance starts with the selection of the steel material. Our premium gate cutters such as our Power-Up line are made using Chrome-Vanadium steel with a unique chemical composition. This steel, only available in Japan is capable of producing a highly engineering  product. This  is the same steel type that are used in advanced culinary and medical cutters where precision and long life performance are the two critical factors

Precise and Consistent  Manufacture

Uniquely crafted and tested through over 50 critical production processes to ensure precise and consistent engineered properties

The standard of workmanship and materials ensures a longer lifetime performance and delivers a cut that is like no other

Quality You Can Trust

Every cutter is individually inspected and tested to ensure reliable performance in use

The result of the process is a product with extreme long lasting sharpness that cut easily through the most demanding materials. Your employees will thank you for this quality tool.

Making the Cut – Compare Cutters

Selecting the right tool for the right job is critical regardless of the industry. Tools like cutters are especially important as they impact the quality of a product and impact the user on a functional level. DME carries cutters that get the job done, exceed the need and cutters that are superior in ergonomic design. Whether you’re only using this tool every few days or eery few minutes will determine your needs. Check out our needs comaprison chart below.

Blade Contour

Flat Face

For general purpose cutting where the sprue is fully accessible or proud of the cutting surface.

Nipper Type (slightly rounded)

For sprue cutting where access to the sprue may be slightly recessed.

Angle Heads

For recessed sprue cutting and access to internal cavities.


For special applications where the sprue is recessed.

Blade Stop

When cutting hard or brittle material it is recommended to use a cutter with a blade stop. Adjusting the stop so the blades stop short of hitting each other will extend the life of the blades.


How much pressure an operator must exert when cutting a sprue or gate is determined by the length of the cutter handle. A handle that is too long for the operator’s hand is difficult to grip while a handle that is too short causes excessive strain. Match the cutter with the operator’s hand and the sprue being cut. Ergonomic handles are an effective way to reduce operator fatigue and decrease the risk of carpal tunnel syndrome. Have a left handed operator? We have left handed gate cutters

Quality Cuts: Power-Up Gate Cutters

The Power-up Cutters are designed specifically for cutting heavy duty large sprues with reduced hand pressure.
The unique design and forging positions the hinge pivot point off-center to create a cam action which increases blade cutting pressure.

Simple mechanical leverage principle reduces the required hand force by up to 50% compared to conventional cutters. The new design of these cutters are ideal for repeat cutting of large, heavy sprues and particularly tough applications such as glass-filled resins.
