Estimated Lifting Force at 24"Hg

Lifting force is calculated from the suction cup diameter and adjusted to 80% vacuum. At sea level, atmospheric pressure is approximately 14.7 PSI. At 80% vacuum, the effective pressure is 14.7 x 0.8 = 11.76 PSI.

Important: Calculated lifting force is theoretical and should not be used as the final working load without applying the correct safety factor. Actual performance depends on surface condition, porosity, acceleration, cup orientation, leakage, vacuum level and application conditions.

Typical Applications

  • Bakery depanning and unloading
  • Food-production automation with metal-detection controls
  • Part transfer where cup shape and mounting interface match the tooling

Why Choose This Cup Style?

Depanner suction cups are selected according to product shape, surface condition, required height compensation and cycle speed. Bellows styles provide more compliance and height compensation, while flat cups are generally preferred where low internal volume and fast release are important.

Material and colour — VFDC423915

This blue metal-detectable depanner cup is a separate special-grade product. Its model does not use the standard -SMI or -STMI material suffix. Check the grade documentation for food-contact compliance and detector performance.

Frequently Asked Questions

What does VFDC423915 mean, including its material suffix?

VFDC423915 identifies a Vacuforce 42mm depanner cup. The material designation DEP refers to blue metal-detectable silicone. This blue metal-detectable depanner cup is a separate special-grade product. Its model does not use the standard -SMI or -STMI material suffix. Check the grade documentation for food-contact compliance and detector performance.

What colour is the VFDC423915 suction cup?

This model is supplied in blue.

What applications suit this depanner suction cup?

Typical uses include Bakery depanning and unloading, Food-production automation with metal-detection controls. Confirm surface sealing, process conditions, cycle rate and handling orientation by testing.

What is the cup size and how should I select a fitting?

The listed cup diameter is 42mm (1.654in). Match the fitting to the Vacuforce cup series and mounting bore; a shared nominal size is not proof of mounting compatibility.

How much theoretical lifting force does VFDC423915 provide?

At the page calculation condition of approximately 24inHg (80% vacuum), the existing estimate is 11.1kg / 25.3lb before any safety factor. This assumes ideal sealing and must not be treated as a certified working load.

Does a similarly shaped cup automatically fit another brand of tooling?

No. Compare actual lip diameter, bellows geometry, mounting interface, material and working conditions before selecting a fit-form-function alternative. Confirm performance by application testing.

Does metal-detectable silicone guarantee detection or FDA compliance?

No. Metal-detectable silicone contains detectable filler, but detection depends on detector settings, product effect, fragment size and process conditions. Confirm food-contact compliance separately for the exact supplied grade.

Is a safety factor required for vertical lifting?

Yes. Use an appropriate engineering safety factor; Vacuforce normally recommends at least 8:1 for vertical lifting. Account for leakage, part acceleration, load orientation and surface condition, and validate safe working load in the application.
