⦁ Thermal Control: Managing heat generation through optimized tool paths and cooling.
⦁ Material Knowledge: Selecting the right plastic and pre-conditioning materials to ensure stability, especially for thin-walled or complex geometries.
Plastics have a high coefficient of thermal expansion and can be sensitive to moisture and tool wear. Our meticulous process ensures tight tolerances and flawless surfaces by:
⦁ Controlling Heat: Precisely managing spindle speeds and feed rates to prevent melting.
⦁ Using Sharp, Specialized Tooling: Preventing tearing and ensuring clean cuts.
⦁ Expert Post-Processing: Applying the right finishing techniques for your material and application.
CNC machined plastic parts offer a superior alternative to metal, providing significant weight reduction, lower cost, and excellent machinability. This makes them a top choice for engineers developing prototypes and end-use parts.
However, with a vast range of engineering plastics available, selecting the right one is critical to your project’s success. This guide outlines key material properties and machinability to help you make an informed choice.
The ideal plastic for your application depends on its operational environment and required performance. Key considerations include:
⦁ Mechanical Load: Will the part bear stress, pressure, or endure wear?
⦁ Temperature Exposure: What is the maximum operating temperature?
⦁ Chemical Resistance: Will it be exposed to solvents, oils, or moisture?
⦁ Dimensional Stability: How critical are tight tolerances?
⦁ Regulatory Standards: Are there specific FDA, UL, or NSF requirements?
These materials are known for their excellent dimensional stability and predictable behavior during machining, making them ideal for high-precision components.

Note: While cost-effective, softer plastics may remain vulnerable to scratches and chemicals without a protective coating.
Bead Blasting
Description: A stream of fine glass beads is propelled at high pressure to create a smooth, non-reflective matte texture.
Best For: Creating a uniform, aesthetic finish that eliminates all visible tool marks on durable materials.
Vapor Polishing
Description: Parts are exposed to a chemical vapor that gently melts the outer surface, smoothing microscopic imperfections to a high-gloss, clear finish.
Best For: Achieving optical clarity on acrylic and polycarbonate parts. Requires strict safety protocols.
Fire Polishing
Description: An skilled technician uses an open flame to melt the surface layer of the plastic, resulting in a smooth, glossy finish.
Best For: Acrylic parts requiring a high-gloss appearance. Critical: This process is not safe for all plastics (e.g., PVC can release toxic chlorine gas when heated).
Wet Sanding & Polishing
Description: A multi-step manual process using progressively finer grit sandpaper (with water) to smooth the surface, often followed by a plastic-safe polishing compound.

Plastic CNC machining is a subtractive manufacturing process where computer-controlled mills and lathes precisely cut away material from a solid block (or “blank”) of plastic to create a custom part.
The process begins with a digital 3D CAD model. This file is converted into a set of instructions (G-code) that guides the cutting tools with extreme precision. This allows for the production of highly complex designs with intricate details and tight tolerances that are critical for industries like medical, aerospace, and semiconductor manufacturing.
CNC machining is ideal for plastic parts that require:
High Precision and Tight Tolerances (as tight as ±0.001″).
Excellent Material Properties from solid, engineering-grade plastics.
Rapid Prototyping and Low-Volume Production without the need for expensive molds.
Superior Surface Finish options compared to other processes like 3D printing.
A Wide Range of Material options, including high-performance plastics like PEEK and Ultem.
The cost of a CNC machined plastic part is not calculated by the hour alone. It depends on several key factors we analyze for every quote:
● Part Design: Complexity, size, and required tolerances.
● Material Choice: Cost of the plastic blank and its machinability.
● Quantity: Volume of parts in the order (economies of scale apply).
● Machining Time: How long the CNC machine needs to run to complete the part.
● Post-Processing: Additional finishes like bead blasting or vapor polishing.
