Reliable Plastic Injection Molding Solutions for Salem, OR Businesses
Manufacturing Excellence in the Willamette Valley
Salem is moving fast.
From the agricultural processing plants that feed the nation to the emerging tech firms in the pursuit of innovation near the State Capitol, business in the Cherry City never stops. But when your production line halts because of a missing plastic component, or when a shipment from overseas arrives with critical defects, “fast” hits a brick wall.
You need precision. You need durability. You need a partner who understands that in the Willamette Valley, moisture resistance and thermal stability aren’t optional features—they are requirements.
We provide Reliable Plastic Injection Molding Solutions for Salem, OR Businesses. We replace supply chain uncertainty with engineering certainty.
We utilize state-of-the-art technology and a highly skilled team to deliver the best results for your projects. Ronningen’s commitment to quality and efficiency makes us a trusted partner for all your plastic injection molding needs in Salem, offering tailored solutions that help your business grow.
Why Salem Manufacturers Choose Professional Molding
In the competitive landscape of Marion and Polk counties, relying on “good enough” manufacturing is a risk you cannot afford. Whether you are designing irrigation components for the valley’s farms or housings for state-contracted electronic devices, professional injection molding offers unmatched advantages.
1. Unmatched Scalability and Speed
Injection molding is the only manufacturing process capable of producing millions of identical parts with extremely tight tolerances. Once the initial mold is created, the cycle time per part can be measured in seconds. This allows businesses in Salem to scale from a pilot run of 5,000 units to full-scale production of 500,000 units without reinventing the wheel.
2. Engineering for the Pacific Northwest
Standard plastics often fail in Oregon’s unique climate. Constant moisture and temperature fluctuations can cause lesser materials to swell, warp, or degrade (hydrolysis). We specialize in selecting engineering-grade resins—like glass-filled Nylon or UV-stabilized Polycarbonate—that withstand the wet winters and dry summers of the region.
3. Cost-Effective Volume Production
While 3D printing is excellent for one-off models, it is cost-prohibitive for volume. Injection molding front-loads the cost into the tooling. Once the tool is paid for, the piece price drops drastically.
3D Printing: $20.00 per part (constant cost).
Injection Molding: $0.15 per part (after tooling).
If you are just starting and need to validate your design before cutting steel, our rapid plastic prototyping service bridges the gap, giving you physical proofs in days, not months.
4. Complex Geometries and Integration
Modern products require more than simple shapes. We can mold complex features like snap-fits, living hinges, and internal threads directly into the part. For applications requiring the strength of metal with the versatility of plastic, we offer insert molding plastic parts. This process encapsulates threaded brass inserts or steel reinforcements within the plastic, creating a bond far superior to post-molding assembly.
The Science Behind the Service: Our Process
We don’t rely on guesswork. We utilize scientific molding principles to ensure consistency. This involves using data-driven sensors to monitor the molten plastic’s behavior inside the mold.
Phase 1: Design for Manufacturing (DFM)
Before a single chip of metal is cut for your mold, our engineers review your CAD files. We look for:
Wall Thickness: Ensuring walls are uniform to prevent cooling stresses.
Draft Angles: Essential for ejecting the part cleanly.
Gate Locations: Optimizing where plastic enters the mold to hide aesthetic marks.
Phase 2: Tooling Fabrication
We build molds tailored to your lifespan needs.
Class 101 Molds: Hardened steel, rated for 1 million+ cycles.
Class 103 Molds: Pre-hardened steel, cost-effective for mid-range volumes (under 500k).
Phase 3: Production and Quality Control
Our machines inject molten polymer at high pressures, filling the mold cavity instantly. We monitor injection pressure, melt temperature, and cooling rates.
Visual Inspection: Checking for flash or color swirls.
Dimensional Check: Using CMM (Coordinate Measuring Machines) to verify tolerances.

Solving an Ag-Tech Challenge in Salem
The Problem: A specialized agricultural equipment manufacturer located near the Salem Municipal Airport faced a critical issue. They produced handheld sensor units used to monitor soil moisture in vineyards across the Willamette Valley. Their previous supplier, an overseas vendor, used a generic ABS plastic.
After one season of use, the housings began to crack. The combination of UV exposure during summer and moisture absorption during the rainy season caused the plastic to become brittle. Returns skyrocketed, threatening the company’s reputation with local farmers.
The Solution: They contacted us for a consultation.
Diagnostic: We identified that the ABS material was not UV-stabilized and had poor hydrolysis resistance.
Engineering: We recommended switching to an ASA (Acrylonitrile Styrene Acrylate) resin, known for superior weatherability and UV resistance.
Optimization: We slightly modified the mold design to add strengthening ribs to the enclosure’s corners, improving impact resistance against drops in the field.
The Outcome: The new parts were put into production within six weeks. Field failures dropped to near zero. The client not only saved money on warranty claims but also marketed the “ruggedized” version of their product at a premium price point.
This is the value of Reliable Plastic Injection Molding Solutions for Salem, OR Businesses. We don’t just make parts; we solve problems.
