Sprue grippers are designed to remove molded sprues and parts reliably in automotive, appliance, medical, and general automation applications.
Their simple, durable construction provides strong gripping force, stable part removal, low weight, high rigidity, and long service life. A range of jaw shapes is available to suit different sprue geometries.

A sprue gripper is a purpose-built pneumatic EOAT gripper for removing runners, sprues and selected molded parts from an injection mold. It is usually chosen for compact size, fast response and a jaw profile that holds the target securely during robot extraction and transfer.
Use a compact sprue gripper when the target has a repeatable geometry, sufficient stiffness and a consistent pickup location. Select the body size and jaw shape around the available mold space.
When gripping a molded part or a fragile feature, confirm allowable force, contact marks and positional variation. Custom jaws, sensors or a different gripper type may be more appropriate.
Confirm the sprue, runner or part dimensions, grip point, draft and expected variation between cycles.
Check mold clearance, approach direction, jaw opening and interference throughout extraction.
Select a jaw shape and gripping force that retain the target without cutting, slipping or unacceptable marking.
Confirm operating pressure, valve arrangement, cycle time and whether part-presence sensing is required.
Best for gripping and removing a sprue, runner or suitable molded feature. It holds the target for controlled transfer and release as part of the robot EOAT.
Use a broader robot gripper for general part handling, or an air nipper when the task is to cut the gate rather than hold and transfer it.
These details allow CRG engineers to identify the body size, jaw type, sensor option and EOAT interface.
The complete EOAT may also use CRG frame and EOAT components, pneumatic fittings, brackets and sensor accessories.
It is a compact pneumatic gripper used on injection-molding EOAT to grip and remove a sprue, runner or suitable molded feature from the mold area.
A sprue gripper holds and transfers the target. An air nipper uses blades to cut a gate or runner. Some EOAT assemblies use both functions.
Sometimes. The part geometry, stiffness, surface requirements and allowable force must be checked. A parallel, three-finger, vacuum or custom gripper may be better for many finished parts.
Send the target drawing or clear photos with dimensions, mold clearance, extraction direction, cycle time, air pressure, robot or EOAT interface and any sensor requirements.
Send the target drawing, grip point, mold clearance, cycle time and EOAT interface.
