The client required 100 units of milled aluminum case in anodizing and with silk printing. As these parts were the first batch to test the market, they had a target price. TEAM MFG could meet their need. We were able to deliver a complete set of parts (upper cover, bottom cover, and activating lever) for less than they could get in Israel.

Al 6061 –T6 has good performance not only for mechanism but also machining, it is not expensive and looks great after anodizing. Also, aluminum is lightweight, it is easy to carry and fix. A 3-axis CNC mill is used to route the profile of this case.
As CNC machining combines precision, durabilitym and flexibility, it is widely used in producing metal and plastic compoments. We have the following considerations, and suggested the customers to go ahead with CNC machining services:
CNC machining can deliver accurate dimensions within microns, it it very suitable for metal case that must fit electronic components, mechanical parts, or assemblies without gaps or misalignment.
CNC machining process can provide smooth surfaces without comprimising the sharp details. It reduce the time and cost for secondary polishing or long-time sand blasting.
A wide range of metals and plastics are suitable for CNC machining, and Al 6061 is one of the most popular machining materials. The designer can base on the devices' function and requirement to choose the materials, as well as adjust the design, as CNC machining usually not relate with the investments of tooling.
Once a CNC program is set, the process guarantees uniform parts across multiple runs.This is essential for ensuring assembly reliability and brand reputation.
When compared to die casting or stamping, CNC machining avoids expensive mold investment. Ideal for startups, prototypes, or custom metal enclosures.
After a thorough cleaning and sandblasting, we process the anodizing progress. This is a passivation technique that adds color while increasing corrosion and scratch resistance. It looks great after anodizing.
Through anodizing an electrochmical process to converts the aluminum surfaces into a corrosion-resistant, durable, and decorative oxide finish. The followings are the main benefits of anodizing:
protect the parts from moisture, salt, chemicals etc. bad enviroment, and extends part's lifespan.
The aluminum surfaces after anodzing(espeically hard anodizing) can be harder to withinsatnd scracth, abrasion, and general wear, ideal for mechanical or high-use componements.
The part after anodizing can in uniform, attractive matter or glossy finish. Beside from clear and black anodizing, the customers can also have the parts in their expected colors.
Anodized products can maintain good heat dissipation, and act as an electircal insulator.
Anodizing is non-toxic, no harmful, and is recyclable.
Easy to clean and maintenance.
Siik printing, we also call it screen printing. It is a process involves creating a stencil (or “screen”) and using it to apply ink onto a substrate (such as paper, fabric, metal or plastic). Below are the pictures we need to print on the cases.
| Defect | Appearance | Causes | Prevention |
|---|---|---|---|
| Misalignment | Print shifted from correct position | Poor fixture setup, screen/part movement, inaccurate alignment | Use stable fixtures, check screen alignment before printing |
| Blurring / Smudging | Edges unclear, design looks smeared | Excess ink, high squeegee pressure, part movement | Control ink volume, optimize squeegee angle/pressure, secure parts |
| Pinholes | Small unprinted spots in design | Dust, clogged screen mesh, improper ink viscosity | Clean surface, filter ink, maintain screen cleanliness |
| Color Inconsistency | Uneven shades, patchy color | Uneven ink distribution, poor mixing, inconsistent curing | Mix ink properly, maintain curing settings, adjust squeegee technique |
| Ink Bleeding / Spreading | Ink spreads beyond design edges | Low ink viscosity, high pressure, poor surface treatment | Adjust ink viscosity, control squeegee pressure, pre-treat substrate |
| Poor Adhesion / Peeling | Ink flakes off or peels after curing | Dirty surface, wrong curing temperature, incompatible ink-substrate combo | Clean part thoroughly, verify curing process, use compatible ink |
| Ghosting (Shadowing) | Unwanted duplicate/light image | Screen shifting, double printing, ink residue | Ensure stable screen setup, clean screen regularly |
| Fading / Weak Print | Print looks too light or thin | Low ink deposit, too fine mesh, low pressure | Use correct mesh size, increase ink deposit, adjust squeegee settings |
| Surface Contamination | Bare spots where ink won’t stick | Oil, mold release agents, fingerprints on part | Clean and degrease surface, handle parts with gloves |
"The milled Al6061 cases looked excellent after black anodizing and silk printing. The surface was scratch-resistant and visually appealing—exactly what we wanted for a premium-feeling medical device enclosure."
