Reliability and Uptime: Inside the Chem-Pak and Haumiller Partnership

News
Chem-Pak runs its aerosol lines on Haumiller machinery. Mike Duane and Andy Kees, with Haumiller's Celeste Jenkins, explain what keeps the partnership working: quality equipment, a strict maintenance program, and the reliable uptime that brands can plan production around.
A contract manufacturer is only as dependable as the equipment on its floor. When a brand hands Chem-Pak a formula, the expectation is simple: the product gets filled correctly, consistently, and on schedule. A lot of what makes that possible comes down to the machinery, and the relationship with the company that builds it.

For Chem-Pak's aerosol lines, that company is Haumiller Engineering. We sat down with people on both sides of the partnership to talk about what makes it work.

Machinery that holds up over time

The first thing the team points to is the equipment itself.

"With Haumiller, you know you're getting the highest quality aerosol machinery on the market," says Mike Duane, Vice President & General Manager at Chem-Pak. "It works the same day one as it does ten years later."

That matters more than it might sound. On a production floor, reliability and uptime are near the top of the list. A line that runs predictably is a line your operators can set up, run, and count on, day after day, without surprises that throw off a customer's schedule.

A strict approach to maintenance

Quality machinery is the starting point. Keeping it running the way it ran on day one is its own discipline, and it is one Chem-Pak takes seriously.

"Maintenance is where I'm very adamant. I'm very strict on maintenance," says Andy Kees, Engineering & Maintenance Manager at Chem-Pak. The team runs a CMMS, a computerized maintenance management system, and follows Haumiller's recommendations to the letter: the right lubricants, the right grease, scheduled upkeep, and the correct changeover parts.

The payoff shows up across the operation. "I'm not going to have my techs working on it all the time. It's not going to be a lot of expense, and it's not going to require me to keep a large inventory of repair parts," Kees says. "I get to have a piece of machinery that I know is working."

That is the quiet benefit of getting maintenance right. Less downtime, lower cost, and fewer parts sitting on a shelf, all of which add up to a line that is ready when a customer's order is.

A partnership built on doing the homework

The equipment and the maintenance only get you so far without trust on both sides, and that runs in both directions.

"We trust that the Haumiller machine, when it arrives, is going to work just the way we discussed, and it does," Mike says. "And on Haumiller's end, they know we do our homework to give them all the details they need to design a machine that's going to work for us."

That trust is mutual. Celeste Jenkins, Equipment Sales Professional at Haumiller, puts it from her side: "I have loyalty to Chem-Pak because I know they have a strong desire to make their product run well and deliver the best product on the market."

Why it works

What comes through from both companies is a shared standard. Haumiller is eager to make sure every machine it delivers is excellent, and Chem-Pak holds itself to the same bar for the products it fills.

"When somebody has that passion, as I also do, to deliver a great product, it just makes an excellent partnership," Celeste says.

For the brands Chem-Pak fills for, that partnership shows up where it counts: aerosol lines that run reliably, fill consistently, and stay ready to meet a schedule.
