CHOOSE THE RIGHT ROUTE

Not every project needs to start from zero.

We first identify the level of differentiation you need, then balance investment, lead time and development risk around that goal.

01

Fastest route

Existing Product Customization

Logo, color, packaging, manuals and market-specific accessories based on a proven product platform.

02

Balanced investment

Platform-Based Modification

Reuse a mature internal platform while modifying the housing, UI, accessories or selected functions.

03

Maximum differentiation

Full Product Development

Create a new small appliance through industrial design, engineering, tooling, validation and production.

THE DEVELOPMENT PROCESS

Seven stages. Clear outputs. Defined approvals.

Stage Brief Overview Estimated Lead Time Related Blog
01 Requirements & Feasibility Assessment

Confirm the product category, target market, core functions, target cost, order quantity and launch schedule. Determine whether the project should use an existing platform modification or full new-product development. Deliverables include a product brief, initial proposal, quotation range and project roadmap.

02 Industrial Design & Product Definition

Define the product dimensions, form, CMF colors and finishes, control method, display method and function combination. Deliverables include approved exterior renderings and a product specification proposal.

03 Appearance Prototype ID

After the model and exterior renderings are approved, an appearance prototype is normally produced to confirm dimensions, proportions, colors, grip and overall appearance. It is not the same as a fully working functional prototype.

 3–4 Working Days Appearance Prototype vs. Functional Prototype vs. T0 Sample
04 Structural Engineering & Functional Prototype MD

After exterior approval, development moves into the internal structure, airflow path, electronic solution, battery, PCB, assembly method and safety design. Structural design and the engineering functional prototype are normally completed within this stage.

 10–15 Working Days What Happens During Engineering Sample Development?
05 Formal Tooling & T0 Trial

After the engineering solution is approved, formal tooling begins. The molds and first T0 trial samples are normally completed within about 40 working days for injection, assembly, structural, tolerance and appearance inspection.

06 T1/T2 Optimization & Production Validation

Based on T0 test results, the molds and product structure are refined through T1/T2 trials, performance testing, reliability validation and mass-production document confirmation. The move from T1/T2 to production normally takes about 15 working days, depending on the modification scope.

07 Mass Production, Quality Control & Delivery

Complete golden-sample approval, incoming-material inspection, first-article confirmation, in-process inspection, finished-product inspection, packing and shipment. The production schedule depends on order quantity, material readiness and packaging requirements.

WHY APPROVAL GATES MATTER

Confirm early. Change with clarity.

Each approval protects the next investment. Changes remain possible, but requests made after a confirmed stage may affect engineering work, tooling cost and lead time.

UNDERSTAND THE SAMPLES

Three samples answer three different questions.

An appearance sample should not be treated as a production-ready unit. Knowing the purpose of each sample prevents incorrect expectations.

01

Appearance Prototype

Used for
Exterior, size, color and ergonomic review
Function
Usually non-functional

Confirms what the product looks and feels like.

02

Engineering Prototype

Used for
Structure, electronics and basic performance
Function
Core functions available

Confirms whether the proposed solution works.

03

T0 Trial Sample

Used for
Formal tooling, injection and assembly review
Function
Near-production construction

Confirms what still needs refinement before production.

PARALLEL WORKSTREAMS

Important work continues around the main timeline.

Compliance, packaging, cost and ownership decisions are planned alongside engineering rather than left until the end.

A

Market Compliance

Target countries, electrical requirements, battery transport and relevant certification paths are considered from the beginning.

B

Packaging & Manuals

Retail packaging, inserts, labels and instructions progress alongside product development and are finalized before trial production.

C

BOM & Cost Control

Materials, battery, display, finish, accessories and packaging are reviewed at key approval gates to keep the target cost visible.

D

NDA & Project Ownership

Confidentiality, design-file use, tooling ownership and maintenance responsibilities can be defined before detailed development begins.

DEVELOPMENT INSIGHTS

COMMON QUESTIONS

Before your development project begins.

Clear answers to the questions buyers usually ask before design and tooling investment.

01What information should I provide before development starts?

A useful starting brief includes the product category, target market, required functions, reference images or sketches, expected quantity, target price and desired launch date. A finished drawing is not required.

02Can we start with only a sketch or product idea?

Yes. We can first translate the idea into a structured requirement brief and evaluate whether an existing platform, a platform modification or a complete new development route is more suitable.

03Is an appearance prototype a working sample?

Usually not. Its purpose is to validate exterior design, size, proportion, color and ergonomics. A functional prototype is created later after internal structural and electronic engineering.

04Why can a modified product be developed faster than a completely new product?

A platform-based project may reuse proven internal structures, electronics and materials. A completely new product requires additional structural, airflow, electronic and safety validation before tooling.

05What happens if we change the design after approval?

Changes remain possible, but requests made after an approval gate may affect engineering work, tooling cost and lead time. The impact is reviewed before the change proceeds.

06Can packaging and certification be handled during product development?

Yes. Market compliance should be considered from the first stage, while packaging and manuals can progress once the product dimensions and configuration are sufficiently stable.
