Weight Checker

The Hefestus Check Weight System optimizes cannabis pre-roll production by ensuring precise and consistent weighing of each cone. Its automation reduces labor costs, eliminating the need for two employees, while its reject system filters out inaccurately filled pre-rolls. Seamlessly integrating into existing machines, its accuracy range promises superior product consistency, benefiting both producers and consumers.

  • Accurately weighs each individual pre-roll cone with precision
  • Assures high smokeabilitiy and consistency in production 
  • Integral rejecter – for out of range weight (over or under desired weight)
  • Easily connects to existing machines as an extended station add-on

Helped Us Meet Demand
It’s given us a more cost-effective option to automate a product SKU that is extremely labor intensive and inefficient to produce. The Aura has helped us meet demand needs and sustain stock on the shelf. The service was great, and this team is extremely friendly. They do their best to set their clients up for success. They also take feedback well, which is nice as a purchaser of their equipment. They want to know how to improve.

Quality Rivals Hand-Rolled
We struggled to find the right one because we fold our prerolls and do not twist them, I think the quality is as close to looking handmade as we can get. We are producing at least 100,000 pre-rolls a week. We also purchased the grinder and absolutely love the grinder.

Working Out Phenomenally
We tried another manufacturer that failed miserably, We were gun shy about another but everything Hefestus said, they did. Their equipment is top notch. The Aura is working out phenomenally,We are meeting all of our expectations and the Aura is doing everything they said. Our efficiency has increased, and the production has increased greatly. We’re saving money and the service has been great. We felt in order to meet our standard and we needed to use yours instead of our machine.

This Machine is a No-Brainer
I would say to anybody that does mass production pre-rolls, this machine is a no brainer. Eliminate your labor, eliminate human error, eliminate lazy employees. And allow yourself to have a piece of equipment that functions properly for you, produces something that's super consistent, and is extremely reliable
