Vacuum clamping fixtures are an excellent solution for materials testing applications, particularly when you have a unique sample that needs to be securely held. These fixtures utilize the power of vacuum to create a reliable and efficient method to hold a sample for materials testing. By creating a vacuum seal between the fixture and the sample, these clamping systems provide a strong grip without the need for mechanical clamps, adhesives, or other traditional fixing methods.
One of the key advantages of using a vacuum-powered sample holding fixture is its versatility. It can accommodate a wide range of packages and samples with varying designs, sizes, and material properties. Whether you are working with delicate and irregularly shaped objects, fragile materials, or even samples with complex geometries, the vacuum clamping fixture can provide a secure and stable hold. Vacuum clamping fixtures are a great solution for materials testing applications where you have a unique sample to hold. The benefit of a vacuum powered sample holding fixture is the ability to be used with various types of packages, depending on their design, size, and material properties.
Vacuum holding fixtures can be used with various types of packages, depending on their design, size, and material properties. Some common type of packages that are suitable for vacuum holding fixtures include:
- Rigid Packages.
Packages, such as boxes, containers or cartons, made from rigid material such as paperboard, plastic, corrugated and metal can be securely held during testing given their defined shape and flat surfaces.
- Flexible Packages.
Vacuum holding fixtures can accommodate flexible packages including pouches, bags, or films. While flexible packages may have irregular shapes and varying dimensions, the vacuum force can conform to their surface and hold them securely.
- Flat Folding Cartons.
The use of vacuum holding fixtures are ideal to secure a flat folding carton to accurately measure the force to open it. This methodology more accurately replicates the process found during the production process.
- Blister Packs.
Vacuum fixtures can be designed to hold a blister pack from the backing card side which allows full access to the blister side for easy access during testing.
- Clamshell Packages.
Vacuum holding fixtures can be designed to secure a clamshell package from underneath while allowing accessibility to the top portion for testing.
- Cups and Bottles.
Cups and bottles incorporating an induction seal can be secured using a specifically designed vacuum holder. The holder is provided with various inserts to accommodate cups or bottles with varying diameters and heights.
- Tray Packages.
Vacuum holders for tray packages allow for the complete seal strength testing of the lidding material as there is no mechanical clamp to interfere with the peel area.
- Fragile Packages.
Packages made from fragile materials such as glass or ceramic are ideal for vacuum holding fixtures as the vacuum force distributes pressure evenly over the package surface. This will minimize the risk of breakage or damage during testing.
