PDF Drawings

A clear engineering drawing often provides everything we need to begin a manufacturing review.

Your drawing should include as much information as possible, such as:

  • Critical dimensions
  • Tolerances
  • Material
  • Thread specifications
  • Surface finish
  • Surface treatment
  • Quantity
  • Special inspection requirements

Microcopy:

Best for: Made-to-drawing CNC and OEM components.

Product Samples

If the original drawing is unavailable, an existing physical sample can help us evaluate the part.

Our team can review:

  • Overall geometry
  • Critical dimensions
  • Threads
  • Connection interfaces
  • Material requirements
  • Worn or damaged areas

We recommend providing application information together with the sample, especially when wear may have changed the original dimensions.

Microcopy:

Best for: Replacement parts and discontinued components.

Photos

Photos can provide a useful starting point when drawings and samples are not immediately available.

Send clear images from multiple angles and include any dimensions, part numbers or application information you know.

Our team can then determine what additional information we need before quotation or production.

Microcopy:

Best for: Initial project evaluation.

Custom Parts From Drawing

01. Drawing Review

Our engineering team reviews your drawing, CAD model, sample or technical information.

We focus on:

  • Component geometry
  • Critical dimensions
  • Tolerances
  • Threads
  • Sealing surfaces
  • Machining feasibility
  • Assembly interfaces

If we identify unclear dimensions or conflicting specifications, we discuss them with you before production.

02. Material Selection

We confirm the required material according to your drawing and application.

Common options include:

  • Stainless steel
  • Carbon steel
  • Alloy steel
  • Aluminum
  • Brass

Material selection should consider strength, corrosion resistance, wear, weight, machinability and operating conditions.

03. Manufacturing Planning

We determine a suitable production process according to the part geometry and quantity.

The manufacturing plan may involve:

  • CNC turning
  • CNC milling
  • Drilling
  • Boring
  • Thread machining
  • Welding
  • Assembly
  • Surface treatment

Planning the process before machining helps improve consistency and avoid unnecessary operations.

04. Prototype Production

For new or critical custom components, customers can begin with prototype or small-batch production.

A prototype allows you to check:

  • Installation
  • Dimensions
  • Thread compatibility
  • Mating surfaces
  • Assembly fit
  • Overall functionality

After you confirm the design, we can prepare repeat production according to the approved specification.

05. Quality Inspection

We inspect critical features according to the drawing and confirmed project requirements.

Depending on the component, inspection may include:

  • Overall dimensions
  • Bore diameters
  • Hole locations
  • Thread dimensions
  • Critical tolerances
  • Surface condition
  • Machined interfaces
  • Visual inspection

Please mark important dimensions clearly on your drawing if they require special attention.

06. Product Samples

After inspection and order confirmation, we prepare the components for international shipment.

We focus on suitable packaging for machined metal products so that surfaces, threads and precision features remain protected during transportation.

For repeat projects, confirmed drawings and specifications provide the basis for future orders.
