2.5″ Line Vac Used In Plastic Part Recovery

I recently worked with an OEM who designed an injection molding machine for their customer. In their design, after the polypropylene parts are formed, they pass through a punch process which creates a scrap piece roughly 1-3/4″ in diameter and 6mm thick but it is very light in weight. The end user was looking for a way to recover these parts in an effort to reduce the amount of waste material in the process but needed an automated solution so they didn’t have to dedicate an operator to manually recover the parts and dump them in the recycle bin. The recovery bin is located close to 25 feet away on the other side of the machining area.

After further discussion,  I recommended they incorporate our Model # 6085 2-1/2″ aluminum Line Vac into their design. The 2.5″ Line Vac has a 2.25″ inside throat diameter which could easily pass the parts and convey them to the collection hopper.

Line Vacs connect to standard ID hose or pipe to create a powerful in-line conveyor

With the recovery bin being located outside of the processing area, they were going to have to run the discharge piping up and over the machines so they were needing something flexible to do so. In addition to the Line Vac, I suggested they use a 30′ section of our 2.5″ conveyance hose. Our conveyance hose is constructed of a durable, clear reinforced PVC, ideal for most general applications and we offer it in 10′ lengths up to 50′, in diameters of 3/8″ to 3″ ID.

Flexible clear PVC hose with smooth bore eliminates material build up.

 

When it comes to moving dry material, like small plastic parts or more abrasive materials like steel shot blasting media, the Line Vacs are the perfect, maintenance-free solution as they have no moving parts or motors to wear out.
