Project Flow Chart

Our 6-Step Development Process

1. Product Discovery & Feasibility

We start by understanding your idea, goals, and target market. Whether it’s a sketch, a concept, or a problem to solve, we evaluate feasibility, clarify the core product intent, and align with business and user needs.

2. Concept Development

We refine your vision into a structured concept. This includes preliminary sketches, architecture planning, risk identification, and design alternatives. Early DFM (Design for Manufacturability) considerations help avoid future roadblocks.

3. Detailed Engineering Design

Our engineers develop complete 3D models and technical documentation. We select suitable materials, define mechanical and electronic components (if any), and ensure every design detail aligns with your product’s functional and manufacturing needs.

4. Prototype Fabrication & Iteration

We produce high-quality prototypes using appropriate methods (CNC, 3D printing, sheet metal, etc.). Through functional testing, feedback, and iterations, we refine performance, usability, and durability until the design is fully validated.

5. Pre-Production & Tooling Preparation

Before mass production, we finalize all design specs for manufacturing. This includes detailed DFM reviews, mold design (if applicable), production jigs/fixtures, BOM optimization, and trial runs to ensure consistency and repeatability.

6. Mass Production & Scale-Up

Using high-precision molds and reliable processes, we manufacture your product with consistent quality. Whether it’s a small batch or full-scale production, KingStar ensures reliable output, tight tolerances, and cost efficiency.

Comprehensive Product Design & Manufacturing Support

As a manufacturer with 15+ years in precision molding and machining, we don’t just design—we build products that work on the production line. Our design support ties every step to manufacturability, so you avoid costly reworks and delays. Here’s how we deliver:

We start by aligning your ideas with what’s possible to build efficiently. Whether it’s a consumer gadget or industrial part, we map out goals (who uses it, what it needs to do) and bake in “can we make this at scale?” from day one. For example, we recently adjusted a client’s plastic housing design to use standard mold sizes—same functionality, 30% lower tooling costs. For more details, please refer to our previous post: Guide To Developing A New Product

Our team balances aesthetics with buildability. We craft ergonomic, visually appealing designs that work with low-volume prototyping and mass production. A medical device client wanted a sleek grip for their tool—we kept the look but tweaked the curvature to fit our injection molding capabilities, cutting 2 weeks from production.

We optimize materials, structures, and assembly for real-world use, complying with DFM principle. Need a steel bracket that withstands 500kg loads? We’ll select the right alloy and design reinforcement ribs that don’t complicate CNC machining. Last quarter, we redesigned a automotive part’s joint structure, reducing assembly time by 40% without sacrificing strength.

We turn designs into tangible prototypes (via 3D printing, CNC, or rapid tooling) to test fit, function, and manufacturability. A robotics client’s first prototype had a tight tolerance issue—we adjusted the CAD model within 48 hours, saving 3 weeks of rework later. Post-prototype, we run thermal, stress, and fit tests to catch kinks before production.

We match your design to the best production method—no guesswork. Whether it’s plastic injection molding (our specialty), CNC machining, 3D printing, or sheet metal, we advise on:

Production Methods: Plastic Injection Molding | CNC Machining | 3D Printing | Sheet Metal Fabrication or More Solutions
Tooling Options: Rapid Tooling | Production Tooling
Material Choices: Plastics | Metals | Elastomers

You can click on the link above to learn more details, and if you are not sure which option is the best fit for your idea, that’s where we come in.

Design handoffs fail 40% of the time—we prevent that. Our team delivers detailed CAD models, tolerance specs, and tooling blueprints. We work directly with our production floor (no middlemen) to set up molds, calibrate machines, and run first articles—so the part you designed is the part that comes off the line.

Our company also offers some design tips/guides/insights for your reference.

As the manufacturer, we implement strict quality standards from design to delivery. We use CMM (Coordinate Measuring Machines) for dimensional checks, surface roughness testers, and even thermal imaging for heat sinks. Last month, this caught a 0.02mm tolerance drift in a sensor housing—fixed before it hit your order.

We sync production timelines with your launch plans. Need 500 units for beta testing? We’ll fast-track with rapid tooling. Scaling to 10k units? Our production lines ramp up without sacrificing quality. A consumer electronics client hit their Black Friday launch thanks to this coordination—no last-minute delays.

Design Optimization

Core Objectives of Structural Optimization

  • Strength: It needs to handle real-world stress—impacts, vibrations, heavy loads—without breaking. For example, a crane hook must hold 10x its rated weight in safety tests.​
  • Stiffness: Too much flex ruins performance. A robot arm, for instance, needs to stay precise, with deflection under load limited to 0.2mm or less.​
  • Lightweighting: Use less material where possible. We’ve seen aerospace parts cut 40% weight this way, slashing fuel use.​
  • Cost efficiency: Simplify shapes to reduce machining time, or switch to cheaper materials that still work. A client’s tooling cost dropped 20% just by tweaking wall thickness.​

Our Go-To Design Methods

  • Topological optimization: Let software figure out the most efficient shape. It removes material that doesn’t bear load—great for new parts, like drone frames or medical device components.​
  • Size tuning: Adjust dimensions (thickness, hole sizes, rib heights) on existing designs. We once optimized a bearing housing by 0.5mm here, 1mm there, and cut stress hotspots by 30%.​
  • Shape refinement: Smooth out problem areas—like rounding sharp corners to reduce cracks, or curving surfaces to spread weight better. Works well for parts that need to look good too, like bike frames.

Applicable Standards

  • ISO standards: ISO 12100 keeps safety front and center—designs must handle both normal use and accidents. ISO 9001 means we document every step, so you can trace how we got there.​
  • ASME codes: For high-pressure parts (like hydraulic cylinders), ASME BPVC sets strict strength rules. ASME Y14.5 makes sure drawings are clear, so factories build exactly what’s needed.​
  • Industry specifics: Aerospace parts follow SAE AS9100 (rigorous fatigue testing), while automotive parts meet ISO 26262 to avoid failures that could cause accidents.
