Custom CNC Machined Metal Parts for Permanent Makeup Pen Manufacturers

From Product Design to Production: Precision Aluminum Components for Premium PMU Devices

YS Precision provides custom metal component manufacturing services for permanent makeup (PMU) device brands in Europe and worldwide.

We help product developers, engineers, and purchasing teams transform their PMU device designs into high-quality production parts through:

• Precision CNC machining
• Engineering process optimization
• Cosmetic surface finishing
• Stable small-volume production

For this project, YS Precision manufactured a series of custom aluminum components for a permanent makeup pen, based on the customer's drawings.

The parts were produced from 6061-T6 aluminum alloy and required precision turning, 5-axis CNC machining, fine surface preparation, and color anodizing to achieve the premium appearance expected for professional beauty equipment.

Project Overview

Custom Manufacturing Partner for PMU Device Development

When developing premium beauty equipment, metal components are not only functional parts — they are also part of the product experience.

PMU device brands usually require components with:

• Premium appearance
• Comfortable hand feel
• Precise assembly
• Consistent colors
• Reliable long-term supply

YS Precision works directly from customer drawings and supports the transition from product design to manufacturing.

Our engineering team reviews:

• Machining feasibility
• Manufacturing processes
• Surface finishing requirements
• Production stability

to help customers reduce development risks before mass production.

Precision Aluminum Machining for Premium Beauty Devices

The components were manufactured from:

Aluminum 6061-T6

This material is widely selected for high-end handheld devices because of:

• Lightweight characteristics
• Good mechanical strength
• Excellent machining performance
• Superior anodizing capability

For PMU equipment, aluminum provides the ideal combination of:

Professional durability + Premium appearance

Optimized Manufacturing Process: Turning First, 5-Axis Machining Second

The customized PMU components contained both rotational structures and complex external features.

Instead of using a single machining method, YS Precision developed a combined process:

Step 1: Precision CNC Turning

Turning was used for cylindrical areas to achieve:

• Accurate diameter control
• Good roundness
• Stable concentricity
• Smooth rotational surfaces

This ensured the fundamental dimensions were controlled before secondary machining.

Step 2: 5-Axis CNC Machining

After turning, selected features were completed through 5-axis CNC machining.

This allowed production of:

• Customized external shapes
• Complex transitions
• Special design details

The combined process improved:

• Dimensional consistency
• Surface quality
• Production efficiency

while maintaining the customer's original product design intent.

Premium Cosmetic Finishing for European Beauty Brands

For PMU devices, appearance directly represents the brand image.

The customer required:

Fine Sandblasting

Creating:

• Smooth matte texture
• Premium tactile feeling
• Uniform appearance

Color Anodizing

Including:

• Black anodized finish
• Pink anodized finish

The anodizing process provided:

• Attractive product appearance
• Surface protection
• Better resistance to daily handling

Surface Preparation: The Difference Between Industrial Parts and Beauty Products

For ordinary mechanical parts, minor machining marks may be acceptable.

However, for PMU devices:

Every visible surface matters.

Before anodizing, YS Precision carefully controlled:

• Tool marks removal
• Burr removal
• Edge finishing
• Surface cleaning

This ensured the final anodized parts met the appearance expectations of consumer-facing products.

Reliable Production Support for 4,000 PMU Pen Sets

For a growing beauty equipment brand, production reliability is critical.

This project required approximately:

4,000 complete sets

To maintain delivery consistency, YS Precision coordinated:

• CNC machining schedules
• Secondary finishing
• Quality inspection
• Packaging preparation

The components were produced according to the customer's production plan and shipped in organized batches.

Individual Packaging for Premium Cosmetic Components

Because anodized aluminum surfaces are sensitive to scratches and handling marks, each component was individually protected before export.

Packaging included:

• Individual protection
• Separation between components
• Safe export preparation

This helped ensure the parts arrived in Europe ready for assembly.
