Q&A: How Automotive Manufacturers Reduce Assembly Downtime by Investing in Horizontal Impact Testing
What is the Horizontal Impact Test System (HITS)?
The HITS consists of two main parts:
- A large sled that runs on a track.
- A bulkhead or vertical surface.
What types of impacts can the HITS replicate?
Our HITS replicates side impacts. The most common are:- Short-duration impact events, such as a truck backing into a dock or a pallet marshalling with a forklift.
- Long-duration impact events responding to railcar coupling.
Is the HITS the best choice for this type of testing?
Essentially, yes. There’s really no other way to replicate in a laboratory the effect of long-duration, high-velocity impacts, such as railcar coupling, other than a programmable horizontal impact sled. And since the HITS can be programmed to replicate both short- and long-duration impacts, conducting both tests at the same lab can save time and money.What types of products and packaging can be tested via HITS?
Many different types of packaging are used in the automotive space. Here are a few common examples:- Metal racks filled with stamped parts, such as doors, door parts, hoods, roofs, and bumpers, which are commonly en route from the stamping facility to the assembly plant.
- Returnable containers, usually plastic bins, pallets, or trays, which are custom designed and thermoformed to snugly fit specific parts.
- Expendable containers, which are similar to the above, but made of corrugated cardboard and intended for one-time use.
Why is it important to test these automotive packaging systems using the HITS?
This testing method assesses whether the packaging can prevent the product(s) from being displaced in the event of an impact. If a truck containing a rack of car parts arrives at an automotive assembly plant, it’s often a robot, rather than a person, who then picks the part out of the rack and moves it to its location. If the part has been knocked out of place, the robot goes down, and the entire system screeches to a halt.Even one hour spent repacking parts that have popped out of their containers in transit can be incredibly costly. Investing in horizontal impact testing up front reduces downtime by ensuring that your packaging and product can withstand every step of the supply chain and keep the process running smoothly, saving both time and money.
