Automation for a New Era of Cannabis Pre-Roll Manufacturing

The phrase “family business” often brings to mind heritage, legacy, and
stability, and Hefestus embodies all three. Based in Israel and serving the
global cannabis market, the third-generation engineering house is rooted in
a tradition of agility and innovation.

This fall, the company is introducing two proprietary technologies poised
to reshape how infused pre-rolls are made and kept fresh.
Patented “donut” infusion for smoother, cleaner draws

Infusion has become a major value driver: Consumers want concentrate-level
potency with a familiar smoking experience. Brands often saturate biomass
with full-spectrum distillate or inject concentrates like rosin or budder
into joints, but those methods can cause clogging, uneven burn, or poor
draw. Kief-coating, or “stardusting,” is typically manual and inconsistent.

Hefestus’s answer is a patented inside-out “donut” infusion method. Instead
of pushing concentrate into the center of a pre-roll, the joint is
engineered with a tiny airflow channel through the core. The result is
consistent burn and a smoother draw without clogging, canoeing, or
sacrificing smokability at higher infusion levels.

The new donut-making equipment provides a fully automated, scalable
solution compatible with multiple formats including pre-rolls, blunts, and
cones. Simple in concept but bold in execution, the system reflects
Hefestus’s core strength: bridging high-precision engineering with cannabis
manufacturing challenges.

MAP technology that preserves freshness and potency

Even when production is dialed in, distribution presents its own obstacles.
Flower and pre-rolls are highly sensitive to oxidation, humidity, and
terpene loss. In food and pharmaceutical packaging, modified atmosphere
packaging (MAP) is widely used to mitigate those issues but cannabis has
been slow to adopt it.

Hefestus’s MAP system flushes ambient air from packaging like tubes, jars,
and multipacks and replaces it with inert gases like nitrogen, dramatically
reducing oxygen and humidity. The benefits: mold prevention, terpene
preservation, and maintained potency. In short, what ships out is what
consumers experience after purchase.

“Once flower is ground and rolled, protective packaging becomes even more
critical,” said Hefestus USA Chief Executive Officer Shahar Yamay. “Proper
MAP sealing helps ensure the pre-roll a customer lights is as fresh as the
one that left the production line.”

The process is both elegant and robust: After a pre-roll is inserted into
its package, the system flushes, seals, and safeguards the internal
atmosphere while still allowing for labeling and visibility. It transforms
packaging from a container into a quality-preservation system.

Automation that scales with modern cannabis operations

In cannabis manufacturing, automation is no longer optional. Brands relying
on manual labor for filling, infusion, and sealing face higher costs,
inconsistent quality, and limited scalability. With decades of automation
experience across food, pharma, and consumer goods, Hefestus brings proven
precision to cannabis operations.

“We stay ahead of the game, we listen to our customers, and we adjust in
real time,” said Head of Business Development Tomer Oliel. “Our goal is to
strengthen our customers’ success through innovation that’s practical and
reliable.”

With technical rigor and real-world usability, Hefestus helps producers
deliver consistency, smoother experiences, and longer shelf
life—engineering progress without losing sight of its roots.

The science behind better pre-rolls

1. What is Hefestus’s donut infusion technology?

Hefestus uses a patented airflow channel at the center of the pre-roll,
enabling higher infusion levels without clogging, canoeing, or uneven burn.
2. How does MAP sealing keep pre-rolls fresh?

The system replaces oxygen with inert gases to reduce humidity, mold
risk, and terpene loss—maintaining the product’s intended experience.
3. Why should pre-roll manufacturers automate?

Automation reduces labor costs, ensures high-volume consistency, and
supports regulatory-grade repeatability that hand-filled processes can’t
match.
4. For what industries has Hefestus engineered?

The company brings decades of automation expertise from food, pharma,
and consumer goods—now adapted for cannabis production.
