CNC (Computer Numerical Control) machining is a subtractive manufacturing technology: parts are created by removing material from a solid block (called the blank or the workpiece) using a variety of cutting tools.
CNC machining is a digital manufacturing technology: it produces high-accuracy parts with excellent physical properties directly from a CAD file. Due to the high level of automation, CNC is price-competitive for both one-off custom parts and medium-volume productions.
Almost every material can be CNC machined. The most common examples include metals (aluminum and steel alloys, brass etc.) and plastics (ABS, Delrin, Nylon etc). Foam, composites and wood can also be machined.
The basic CNC process can be broken down into 3 steps. The engineer first designs the CAD model of the part. The machinist then turns the CAD file into a CNC program (G-code) and sets up the machine. Finally, the CNC system executes all machining operations with little supervision, removing material and creating the part.
Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession.
Polyurethane reaction injection molding (RIM) technology was developed in the late 1960s. Since then, the technology has evolved dramatically as more and more product designers and manufacturers have learned to tap the unique capabilities and benefits of RIM for an ever-growing range of products. The universal physical characteristics of polyurethane RIM parts are high strength and low weight. It’s helpful to view RIM not as a specific resin with narrowly defined properties, but as a process capable of achieving a broad range of properties. As its name implies, the polyurethane RIM process uses polyurethanes to produce molded parts. The polyurethanes begin as two liquid components, compared with the pellet form of most thermoplastics. These liquid components – an isocyanate and a polyol – are developed in two-part formulations, which are often called polyurethane RIM systems.
Depending on how the polyurethane RIM system is formulated, the parts molded with it can be a foam or a solid, and they can vary from flexible to extremely rigid. Thus, polyurethane RIM processing can produce virtually anything from a very flexible foam-core part to a rigid solid part. Part density can vary widely, too, with specific gravities ranging from 0.2 to 1.6.
We offer our customers an advanced assembling department where systems and sub-systems design and production projects are carried out according to the customer’s requirements. The assemblies can be made in the turn-key format, including integration of sub-systems into larger technology embedded systems. We provide assembly services for the various systems we manufacture in our plant.
