The Plastics Industry in Spokane Valley
Plastic components are everywhere, from medical devices and electronics enclosures to automotive parts, packaging, and consumer goods. In Spokane Valley, a cluster of plastics manufacturers designs molds, produces injection-molded parts, thermoforms heavy-gauge components, and fabricates custom plastic products for customers across the country.
Many of these companies operate out of the Spokane Industrial Park on Sullivan Road and other industrial zones near Interstate 90. Their proximity to electronics, aerospace, and medical manufacturers in the region creates natural partnerships, and local production allows customers to reduce lead times and shipping costs compared with overseas suppliers.
Key Plastics Manufacturing Processes
Injection molding produces high volumes of precise, repeatable parts. Thermoforming and pressure forming shape heated plastic sheets into larger components such as panels and housings. Mold making and tooling are critical upstream services, while fabrication, machining, and foam conversion add flexibility for custom and low-volume projects.

Plastics Industry Trends
Sustainability is reshaping plastics manufacturing. Customers increasingly request recycled resins, bio-based materials, and designs that use less plastic. Medical device manufacturing continues to grow, demanding clean production environments and strict quality controls. Automation, including robotic part removal and vision inspection, is improving consistency. Reshoring has also brought more tooling and molding work back to North American suppliers seeking supply chain stability.
How to Choose a Plastics Manufacturing Partner
Match the manufacturer's capabilities to your part size, volume, and material requirements. Ask about quality certifications, such as ISO 9001 or ISO 13485 for medical work. Discuss tooling ownership, maintenance, and expected tool life. Request design-for-manufacturing feedback early, since small design changes can dramatically reduce costs. Finally, evaluate communication and project management, which are crucial during prototyping and launch.
Frequently Asked Questions
How much does an injection mold cost?
Mold costs vary widely based on part size, complexity, number of cavities, and steel type. Simple prototype molds can be relatively affordable, while complex production molds represent a significant investment. Discussing volumes and design details with a local molder early allows the team to recommend the most cost-effective tooling approach for your product.
What is the difference between injection molding and thermoforming?
Injection molding forces molten plastic into a closed mold and is ideal for complex parts produced in high volumes. Thermoforming heats a plastic sheet and shapes it over a mold, which works well for larger parts and lower volumes with less expensive tooling.
Can plastic parts be made from recycled material?
Many applications can use recycled or blended resins, although performance requirements and regulations may limit their use in medical or food-contact products. A manufacturer can help evaluate suitable materials.
Do local molders help with product design?
Many offer design-for-manufacturing reviews that improve part quality and reduce cost before tooling begins.
