How We Begin

Two Starting Points for Your Project

COMCO supports projects at any development stage, from early napkin sketches to dual-sourcing exact matches.

Point A · Innovation

New Product Development

You bring an idea, hand sketch, functional specification, or 3D rendering. Our engineering team translates the concept into production tooling, material formulation, and functional prototypes.

Concept feasibility & structure calculation
Custom PVC/TPU material formulation
Rapid 3D modeling & mockups
Iterative sampling until final buyer sign-off

Existing Product Sample for Second Sourcing

Point B · Second Sourcing & Optimization

Existing Product Improvement

You have an existing SKU and seek a reliable second supplier, lower production cost, improved seam integrity, or packaging volume reduction for global retail logistics.

Exact dimensional and material reverse-spec
Value engineering to hit retail target cost
Packaging & carton cubic feet optimization
Full compliance lab testing against ASTM / EN71

Process in action

From Direction to Production

A real look at how an innovation concept develops from initial brief through engineering, physical sampling and refinement into volume production.

01

Draft Design

Initial concept sketch and functional layout exploration.
02

Engineering

Structural calculation, material specification and 3D modeling.
03

1st Draft Sample

Physical non-inflatable pool prototype built for proof of concept.
04

Final Sample

Refined structure, tested for pressure stability and user experience.
05

Volume Production

Tooling completed and standardized manufacturing in volume.

Real R&D Proof

We Don't Just Make Products. We Rethink Them.

In 2020, backyard pools required constant inflation pumps or tedious steel frame assembly. COMCO spent 2 years and 20–30 prototype revisions developing a quick-unfolding Non-Inflatable Pool with patented internal HDF core support.

Turnaround Timeframe

Rapid Physical Sampling Before Tooling

A dedicated 20+ person prototyping workshop with pattern cutting, high-frequency welding machines and sewing stations dedicated purely to pre-production sampling.

2–3 Days Standard Inflatable Sampling For existing pool floats, swim rings, beach balls and simple air chambers with stock PVC film.

7–10 Days Custom Pattern & Print Samples Including custom cylinder screen printing, special valve tooling, and fabric-covered sewing patterns.

10–15 Days Complex & Drop-Stitch Products High-pressure SUP boards, air tracks, complex water slides, and structural multi-chamber frame pools.

Engineering Pillars

Engineering For Function, Cost & Compliance

Our engineers do not simply replicate drawings; we optimize structure, resin formulation and assembly efficiency.

01 / STRUCTURE

Stress & Seam Integrity

Optimizing HF welding die widths and corner radiuses to prevent air and water leaks under severe dynamic pressure loads.

02 / MATERIAL

Custom Calendering Formulation

With in-house PVC film calendering, we adjust plasticizer ratios, cold-crack resistance (-25°C), and UV stabilizers directly.

03 / COST

Value & Target Cost Engineering

Restructuring material thickness, carton dimensions, and container load optimization to help retail programs hit shelf target price points.

04 / COMPLIANCE

Regulatory Pre-Screening

Pre-testing incoming raw materials in our chemical laboratory for Phthalates, REACH SVHC, Lead, and CPSIA compliance before cutting.

Frequently Asked Questions

Product Development FAQ

Answers to common questions international brand buyers and retailers ask when starting a project with COMCO.

What information do I need to submit to start a new product?

You can start with as little as a reference photo, hand sketch, or target dimension. If you have 3D CAD files (STEP, IGES, STL) or tech packs with specific PVC thickness and Pantone colors, our engineers can review them directly.

Can COMCO develop from a physical sample or competitor reference?

Yes. Many brand clients send us physical benchmark samples for second-sourcing or product refinement. We measure exact dimensions, analyze film thickness and formulation, and produce counter-samples for approval.

How long does physical prototype sampling take?

Standard inflatable products take 2–3 days using stock film. Custom printed or fabric-covered items take approximately 7–10 days. Complex drop-stitch boards and structural pools take 10–15 days.

Can our product design and IP be protected by NDA?

Absolutely. We routinely sign Non-Disclosure Agreements (NDAs) with global brands and retailers before reviewing CAD files or project briefs. Custom tooling and molds remain exclusively reserved for the paying client.

Can COMCO help optimize an existing product to meet a target cost?

Yes. Our engineering and production teams specialize in Value Engineering. By optimizing high-frequency welding seam lines, adjusting PVC formulation, and redesigning master carton palletization, we help customers achieve strict retail price points.
