Have questions about injection molding, tooling, or product engineering? Our team at Lincoln Tool & Design works with customers every day to design, build, and support precision tooling and manufacturing solutions. Below are answers to some of the most common questions about our capabilities, processes, and services to help you better understand how we approach complex manufacturing challenges.
We support a wide range of industries that require precision tooling, custom machines, automation, and plastic injection molding. Our experience in tight-tolerance machining, mold building, fixture design, and controls integration allows us to handle both straightforward and highly complex manufacturing challenges.
Yes, we operate multiple CNC mills and CNC lathes in-house, along with manual machining centers, wire EDM, plunge EDM, grinding, heat treating, fabrication, welding, and assembly. Keeping these capabilities under one roof allows us to maintain quality control, reduce turnaround time, and ensure seamless coordination between engineering and production.
We are capable of machining tooling and components to very tight tolerances, in certain applications as precise as plus or minus .0001 inch. Tolerance capability depends on material type, geometry, part function, and overall design requirements. During tool build, we use advanced CNC machining, EDM processes, grinding, and heat treating to maintain precision. We verify dimensional accuracy using CMM systems, Keyence inspection technology, optical comparators, and hand gauging to ensure both tooling and molded parts meet specification.
We use a range of inspection and quality equipment to verify dimensional accuracy. Our capabilities include CMM systems, Keyence IM inspection technology, handheld CMM systems, optical comparators, and traditional hand gauging methods. These tools allow us to confirm that tooling and molded parts meet specification before delivery.
Product engineering services involve the design, development, and improvement of products and manufacturing systems. We offer design engineering, reverse engineering, tooling and fixture design, custom machine development, automation integration, and controls programming to help move projects from concept to production.
Product engineering typically begins with concept development or evaluation of an existing design. From there, we create detailed 3D models using platforms such as SolidWorks and PTC Creo, refine the design for manufacturability, and coordinate closely with our fabrication team. Projects may also include automation design, controls development, panel building, PLC and HMI programming, and robotic integration before final production launch.
Yes, our engineering team works closely with customers to evaluate and improve part designs. Whether starting from scratch or refining an existing concept, we provide design engineering, tooling and fixture design, and manufacturing guidance to ensure the final solution performs reliably in production.
Yes, we design and build molds in-house at our facility in Lincoln, Nebraska. Keeping mold design, machining, assembly, and qualification under one roof allows us to maintain close collaboration, strong quality control, and clear communication throughout the entire project. Building domestically also gives our customers better visibility into timelines and performance from start to finish.
Prototype tooling is designed for testing, validation, and lower production volumes. It allows customers to evaluate form, fit, and function before committing to full-scale production. Production tooling is engineered for repeatability, durability, and higher volumes over an extended lifecycle. It is built to maintain tight tolerances and consistent part quality over time.
Injection molding supports a wide variety of thermoplastic materials depending on the performance requirements of the part. Material selection is influenced by strength, flexibility, temperature resistance, chemical exposure, and regulatory considerations. We work with our customers to ensure the mold is designed to support the appropriate material for the intended application.
DFM stands for Design for Manufacturability. It is the process of reviewing and refining a part design to ensure it can be produced efficiently, consistently, and cost-effectively. By considering draft angles, wall thickness, material flow, and tooling complexity early in the design phase, we help reduce production risk and improve long-term performance.
Lead time depends on the size and complexity of the mold, material requirements, and overall project scope. Simpler tools can move through design and build more quickly, while complex molds with tight tolerances or automation components require additional coordination. Because our engineering and fabrication teams work closely together, we focus on strong project management to deliver tools on time and to specification.
The cost of an injection mold depends on the complexity of the part, the number of cavities, required tolerances, materials, and expected production volume. Prototype tooling is typically a lower initial investment, while full production tooling designed for long-term durability requires more engineering and build time. We work closely with our customers to develop a tooling solution that balances cost, performance, and long-term value.
Yes, we offer pad printing, plastic part machining, heat staking, and assembly of components. These services allow us to offer our customers a level of finished product to best suit their needs. This improves their efficiency, reduces their internal processing time, and gets products to their consumers faster.
Yes, we provide tooling maintenance and repair services. Routine maintenance helps extend tool life, protect part quality, and reduce downtime. Because we have in-house machining, grinding, EDM, and inspection capabilities, we can efficiently evaluate and address tooling issues to keep production running smoothly.
