GM and Ventec Life Systems partnered to produce critical care ventilators in response to the COVID-19 pandemic.
The 50th annual Automotive Innovation Awards program includes a new category — Industry Solutions for COVID-19. Here are the finalists.

The 50th annual Automotive Innovation Awards, organized by the Automotive Division of the Society of Plastics Engineers (SPE), includes a new category this year — Industry Solutions for COVID-19.

In the early days of the pandemic, carmakers stepped up — some taking a quasi wartime footing — to produce personal protective equipment, ventilators, and various medical parts that were in short supply. Industry experts and a blue ribbon judging panel selected 10 finalists worthy of recognition in this category. The winners of this and numerous other categories more directly related to automotive innovation will be announced during a gala presentation on Nov. 10, 2021, in Livonia, MI. Here's more information about the event in case you are interested in attending.

PlasticsToday will report on the winners following the gala next week. In the meantime, here are the finalists in the COVID-19 category along with a description of their achievements provided by SPE.

Ventilator Main Chassis Production

Material Supplier/Toolmaker: Avient Corp./Proper Group International Inc.

Material: Versollan OM1262NX-1 TPE

Process: Injection molding

The team developed a unique TPE offering modified flow, high adhesion to a PC/ABS substrate, and chemical resistance, and shipped it within 24 hours. High-cavitation tooling was rapidly produced to ensure sufficient supply. A robust supply chain was established that met demand throughout 2020.

Warpage Correction in Ventilator O2 Bracket

OEM Make & Model: 2020 General Motors Co./Ventec Life Systems V+Pro Emergency Ventilator

Tier Supplier and Processor: PTI Engineered Plastics

Material Supplier/Toolmaker: Victrex PLC /PTI Engineered Plastics

Material: Vitrex 450FC30 PEEK

Process: Injection molding

In less than one week, the PEEK resin was fully characterized for CAE material cards, and tooling for a key ventilator component was redesigned using mold morphing/windage techniques to address warpage issues that had previously required post-mold fixturing and machining. New tooling was produced and first parts were shot nine days later, allowing the team to hold extremely tight tolerances without post-mold countermeasures. This enabled production to be scaled from thousands/year to thousands/week to meet high demand. Costs were reduced 30 to 40% by eliminating post-mold machining.

Ventilator Diaphragm

OEM Make & Model: 2020 Ventec Life Systems V+Pro Emergency Ventilator

The team used its automotive skill set to retrofit processing equipment to switch from optical-grade silicone to conventional liquid silicone rubber, solve a void issue, and build new tooling in just 19 days. Production of a critical ventilator diaphragm was ramped up from 1,000/year to 4,000/week. 

Powered Air-Purifying Respirator (PAPR)

OEM Make & Model: 2020 Ford Motor Co. Limited-Use PAPR

Tier Supplier/Processor: Ford Motor Co./Denso Corp.

Material Supplier/Toolmaker: Asahi Kasei America Inc., Celanese/3Dimensional Services, Protolabs

Material: PPTD40, POM Asahi P-40TC-1102 NT101, Celanese M90 CF2001 PolyPro, POM

Process: Injection molding

The team produced the first all-plastic PAPR, personal protective equipment used by medical workers, converting previously metal components to plastic to reduce mass and costs and improve user comfort. The lighter, more-efficient design improved battery life, enabling workers to complete a 12-hour shift without needing to recharge the battery. NIOSH certification was achieved in just three days on the first try. Production was increased to 8,500 units/week from the 650/week the previous supplier achieved. All profits from sales were donated to COVID-19 relief funds, and four patents are pending on the unit.
