CAPABILITIES

What We Can Help You Make

Manufacturing support for detailed custom components, from the first prototype to repeat small-batch orders.

CNC Machining

Precision CNC milling and turning for custom aluminum, brass and stainless steel components.

Precision Engraving

Fine machining and engraving for parts where detail, geometry and appearance matter.

Surface Finishing

Finishing options selected for appearance, protection and the final feel of each component.

Prototypes & Small Batches

Flexible manufacturing for prototypes, limited runs and repeat small-batch orders.

MILLING & TURNING

CNC Machining

We support custom CNC milling and turning for detailed metal components manufactured from customer-supplied drawings, CAD files and specifications.

Whether the project requires a single prototype, a limited production run or repeat small batches, the manufacturing approach is reviewed according to geometry, material, tolerances, finish and quantity.

  • CNC milling and turning
  • Custom threads and internal features
  • Detailed external geometry
  • Prototype and repeat small-batch projects
  • Made from customer-supplied CAD files and drawings

DETAIL & APPEARANCE

Precision Engraving

Engraved lines, patterns, markings and machined surface details can be incorporated when appearance and definition are important to the finished component.

Engraving requirements are reviewed together with material, geometry, depth, surface finish and production quantity.

  • CNC-machined decorative details
  • Geometric patterns and surface features
  • Identification or functional markings
  • Suitable for custom and limited-run components

FINAL APPEARANCE

Surface Finishing

Surface finishing is selected according to the component material, appearance, protection and intended use. Available options depend on part geometry and project requirements.

  • Bead blasting
  • Brushed finishing
  • Polishing
  • Anodizing
  • Plating
  • Passivation
  • Other finishes reviewed by project

FLEXIBLE PRODUCTION

From Prototype to Repeat Small Batches

GRACTS is structured around detailed custom projects that may not be an ideal fit for high-volume production suppliers.

We support early prototypes, limited production runs and repeat small-batch orders, with the manufacturing route reviewed according to the actual project.

COMMON MATERIALS

Materials We Commonly Work With

Aluminum

Common choices include 6061 and 7075, depending on strength, machining, finishing and project requirements.

Brass

Suitable for detailed components where appearance, weight, machinability or a distinctive metal finish is important.

Stainless Steel

Used for components requiring strength, corrosion resistance, wear resistance or a premium metal appearance.

Other materials can be reviewed according to drawing, quantity and application.

INSPECTION

Quality Checked Against Your Requirements

Key dimensions, fit, appearance and finishing requirements are reviewed according to the customer's drawing and agreed project specifications.

Inspection methods are selected according to the feature, tolerance and project requirements.

  • Dimensional inspection
  • Thread and fit checks
  • Surface and appearance review
  • Drawing-based verification
  • Pre-shipment inspection
