Engineering Capabilities

Before production, Sanjin turns drawings, materials, and package constraints into controlled manufacturing plans.

Every drawing carries hidden manufacturing questions.

We translate visible requirements into the process risks that must be understood before tooling, sampling, or production begins.

What the project states

  • Drawing
  • Material
  • Tolerance
  • Volume
  • Application

What engineering must uncover

  • Forming risk
  • Warpage or burr
  • Expansion or shrinkage
  • Tooling reference
  • Inspection method

A sample only matters when the process can repeat.

How risk becomes control.

Tooling and fixture control

Controls geometry, forming paths, datum references, handling stability, and repeatable positioning.

Material and thermal behavior

Controls expansion, shrinkage, sealing conditions, stress response, and temperature-driven process risk.

Inspection and process windows

Controls measurable acceptance criteria from sample approval through ramp-up and volume production.

Beyond standard parts.

Standard products provide a starting point. When a design requires a different geometry, interface, material behavior, or delivery format, our engineering team helps turn that requirement into a manufacturable specification.

Geometry

Openings, steps, bends, deep-drawn features, edge structures, and custom dimensions.

Material compatibility

Kovar, copper alloys, Alloy 42, stainless steel, ceramic, glass, and selected molding materials.

Surface & interface

Plating requirements, soldering surfaces, sealing areas, contact points, and functional interfaces.

Delivery format

Tape and reel, trays, bulk packing, clean handling, and project-specific packing.

From first drawing to production release.

We keep the path visible from the first drawing discussion to sample approval and stable production.

Clarify the requirement

We align drawings, target use, expected volume, and critical features before choosing a manufacturing route.

Identify the control points

We define which dimensions, surfaces, material behaviors, or handling steps need special attention.

Choose the production route

Tooling, fixtures, inspection methods, and packing formats are selected around the approved requirement.

Confirm the first articles

Samples and first article checks verify that the agreed route can produce the required result.

Release with traceability

Once approved, production moves forward with inspection records, handling controls, and lot-level traceability.

Explore solution paths.

Sanjin’s engineering work connects directly to three package solution paths: precision metal components, hermetic and ceramic structures, and high-power molded platforms.

Precision Stamping & Tooling Build-to-print metal components, lids, frames, shims, and lead-frame structures. → Hermetic Sealing & Ceramic Integration Glass-to-metal seals, metallized ceramics, and protected package structures. → High-Power Plastic Packaging Molded package platforms engineered around thermal dissipation and production-ready tooling. →
