MMT Chats: Vials for the Vaccine/Antibody Testing

COVID has made work a little more challenging but it is also teaching teams “to do things a little bit differently” so they can turn jobs around a lot faster. MMT Editorial Director Christina Fuges chatted with one Illinois mold builder and molder who did not take on PPE, but instead, focused on tooling for vials used to collect DNA for vaccine/antibody development.

Tri-Par Die & Mold Corp. has been doing work for the medical research industry for about 12 years, so the complexity and meaning of medical work is not lost on this team. However, when one of its West Coast customers dropped seven new molds on the team for making vials to collect DNA specifically to aid the development of a vaccine /antibody for the virus, they gladly accepted the challenge to deliver in 12 weeks.


Tri-Par Die & Mold’s General Manager David Plocinski and Marketing and Sales Manager Rita Baranowski join MoldMaking Technology’s Christina Fuges for a quick MMT Chat about COVID-19.

These vials require hot runner molds.  To date, the biggest challenge to achieving their quoted lead time has been getting the hot runner suppliers to turn their delivery around more quickly.

“Hot runner suppliers are the critical path in terms of getting all these molds out. The customer wants the molds in 10 weeks; we quoted 12 weeks because of the hot runner lead times. The customer is offering us thousands of dollars for every week early,” GM David Plocinski says.

Adding to the challenge is the fact that these vials are very challenging, they are about 3/8” in diameter by an inch-and-a-half long. They are very thin-walled tubes. At some points, the wall thickness gets down to 0.008 thick, according to Plocinski.

In molding, “you get a lot of pressure build-up, so it is essential that the hot runner drops and nozzles can withstand that kind pressure. The machines that are running these molds are filling the parts in a fraction of a second. Cycle times for the 8-24 cavity molds are sub-10 seconds.” Plocinski says.

As they wait for the hot runner system, Tri-Par Die & Mold and its network of shops are completing what they can on the molds.

“The lead time on these molds are short, so we are utilizing a network of vetted shops in the area with which we have relationships (through the AMBA Chicago Chapter) to help us shorten the deliveries on some of these tools,” Plocinski says. “We have three mold shops working on these molds to get them built and delivered.”

Taking Action

With a combination of employees and temporary workers, business has been “steady slow” for this South Elgin, Illinois mold builder and molder.

Strategically scheduling the staff at Tri-Par Die & Mold has helped the team implement social distancing and more in-depth cleaning processes. Plocinski also mentions that their regular style of stand-up production meetings has proven even more efficient during these trying times.

“Standing meetings are more productive, quicker, and allow everyone to get to the point. Plus, it also helps us to naturally practice social distancing,” Plocinski says.

“Taking action” with critical COVID-19-related work and communication have been vital to employee morale these days. An attitude of “working together to get through this” is evident throughout the 60,000-square-foot facility the team moved into about five years ago.

Tri-Par Die & Mold offers mold construction and injection molding for an array of industries, including the medical, food container, water purification, and automotive lens markets.

A five-person tool shop is dedicated to new molds and repair, with 24-hour, five-day-a-week production molding using its 26 molding machines (ranging from 50 tons up to 720 tons).

“Our diversified business model provides a tremendous variety of customers and experiences that regularly puts our team to the test in developing solutions,” Plocinski says. “We are fortunate to work with customers who do research and push the envelope, and we are committed to incorporating what we learn from each job into all of our new tooling.”
