Streamline Your Production with Our CNC Machining Services and Rapid Turnaround

Our CNC machining services streamline the creation of custom phone cases with precision and efficiency. Here's a breakdown of our comprehensive process:

CNC Machining Service Process:

Step 1: Injection Molding

We start by crafting the raw case with a robust injection mold, laying the foundation for the subsequent customization steps.

Step 2: Pattern Printing

Designs are printed onto durable 3M PVC material, ensuring high-quality visuals for the case.

Step 3: Die-Cutting

The printed PVC is then meticulously die-cut to fit specific phone models perfectly.

Step 4: PVC Application

The die-cut PVC is adhered to the raw case, with options to add decorative elements such as glitter, foil, or other inclusions.

Step 5: Resin Application

The CNC Machining Processes: Milling and Turning with Precision

Discover the intricacies of CNC machining processes that transform solid materials into precision parts. Here's an overview of our capabilities in CNC milling and turning:

CNC Milling:

CNC milling is a subtractive manufacturing process that meticulously removes material from plastic and metal blocks to create the final parts.

Utilizing both 3-axis milling and 5-axis indexed milling techniques, we are able to tackle complex geometries and intricate designs.

Explore Our Milling Capabilities:

Dive deeper into our extensive CNC milling capabilities that allow for high precision and versatility in part production.

Review Our Milling Design Guidelines:

We drop transparent resin onto the case for a sleek finish, or mix it with glitter or foil if additional embellishments are needed.

Step 6: Curing Process

The case undergoes baking in an oven until the epoxy resin solidifies, completing the manufacturing process.

The end result is a fully integrated phone case with materials that are permanently bonded, ensuring lasting quality and durability.

Your Guide to Frequently Asked Questions on CNC Machining

Navigating the world of CNC machining can be complex, which is why we've compiled a list of frequently asked questions to help you understand the process, costs, and capabilities involved.

How much does CNC machining cost?

Prices for CNC machining start around $65 and vary based on factors such as complexity, quantity, and lead time. The most accurate way to determine cost is to submit a 3D CAD model for an interactive quote, which includes design for manufacturability (DFM) feedback. Our use of proprietary software and automated fixturing processes means there are no upfront non-recurring engineering (NRE) costs. This pricing model makes low-volume orders cost-effective. Compared to 3D printing, CNC machining prices are similar or slightly higher, but offer improved material properties and surface finishes.

What types of threading options are available?

We provide a variety of threading options, including UNF, UNC, and metric threads, as well as coil and key inserts (note: we do not supply or install the inserts). These threading types are available for both milled and turned CNC parts. For a comprehensive view of our threading capabilities, please visit our website.

What is the maximum part size for CNC machining

What is the maximum part size for CNC machining?
