Expert CNC Milling Services for Custom Acrylic Epoxy Phone Holders

our company, we specialize in CNC milling services that bring your custom designs to life, including the creation of sophisticated acrylic epoxy phone holders. Here's an insight into the components and production process:

Components of an Acrylic Epoxy Phone Holder:

Acrylic Pedestal: The base of the phone holder, molded to precise dimensions for stability.

PET (Polyethylene Terephthalate): A durable and versatile plastic used for high-quality printing.

Double-Sided Adhesive: Ensures a secure bond between the PET and the acrylic pedestal.

Eco-Friendly Ink: Utilized for vibrant and sustainable pattern printing on PET.

Epoxy Resin: Provides a clear, protective coating for the PET layer.

Metal Ring: Adds functionality to the phone holder for easier handling or display.

Production Process Overview:

Step 1: The acrylic pedestal is formed using a precision mold.

Step 2: Patterns are printed onto the PET layer using eco-friendly inks.

Step 3: Double-sided adhesive is applied to PET, which is then die-cut to the pedestal's shape.

CNC Milling Design Guidelines and Capabilities by LK tools

At LK tools, we provide comprehensive guidelines for CNC milling to ensure optimal part manufacturability, aesthetic quality, and efficient production. For an in-depth look at all our design guidelines, we invite you to visit our dedicated page. Below are some key considerations and capabilities:

Maximum Milling Dimensions:

The maximum milling depth available is 2 in. (50.8mm) from either side of the part.

For material-specific milling dimensions, refer to our detailed charts on maximum part extents.

Material-Specific Maximum Dimensions (US and Metric):

3-axis Hard Metals (Titanium, Stainless Steels, Alloy Steel)*: Up to 10 in. x 7 in. x 1.75 in. (254mm x 178mm x 44.5mm).

3-axis Brass and Copper: Up to 10 in. x 7 in. x 2.75 in. (254mm x 178mm x 69.9mm).

3-axis Aluminum and Plastic: Up to 10 in. x 7 in. x 3.75 in. (254mm x 178mm x 95.3mm).

3-axis ABS, Acetal (Two-sided machining only): Up to 10 in. x 14 in. x 1.75 in. (254mm x 356mm x 44.5mm).

Step 4: The die-cut PET is affixed to the pedestal, with options to add decorative elements.

Step 5: Transparent epoxy resin is applied to the PET for a smooth finish.

Step 6: The pedestal is baked, solidifying the resin for a durable finish.

Step 7: The metal ring is assembled to the holder.

Step 8: Double-sided adhesive is placed on the holder's back for mounting.

Upon completing these steps, the materials are fused into a single, enduring unit. The epoxy process ensures a strong bond, akin to the creation of amber.

Understanding CNC Milling: The Subtractive Manufacturing Process

CNC milling is a fundamental subtractive manufacturing technique that shapes raw material into finished parts. Here's an overview of how the CNC milling process unfolds:

Material Fixturing: The process begins by securing a block of metal or plastic material inside the CNC milling machine.

Programming and Milling: Using G-code, the CNC machine is programmed to rapidly and precisely mill the part out of the raw material block. The code directs the milling tools on their paths and dictates the exact movements needed to produce the part.

Advanced CNC Machines: Our sophisticated 3- and 5-axis CNC machines are outfitted with diverse toolsets that enhance both efficiency and production speed, allowing for complex geometries and precise detailing.

As-Milled Finish for Plastics: Machined plastic parts typically retain the as-milled finish, which means tool marks from the milling process may be visible on the surface of the part.

Finishing Options for Metals: For metal parts, there are additional finishing choices available, such as anodizing and chromate plating, to enhance the appearance and durability of the parts.

Final Steps and Shipping: Once the milling run is complete and the desired surface finish is applied, the parts are packaged and shipped promptly to their destination.

CNC milling transforms a simple block of material into intricate parts that meet your design specifications. Whether your project requires basic as-milled finishes or more sophisticated post-processing, our CNC milling services are designed to deliver precision parts with a swift turnaround.
