Hands-on mechanics and physics exhibits installed across a science museum floor
Shanghai Inertia · Exhibit manufacturer

We build exhibits.
Only exhibits.

2,000+ standard models, custom fabrication and OEM for science museums, children's discovery centres, planetariums and public-space commissions. We do not take fit-out contracts. We do not run venues. We do not sell consulting.
That focus is the product.

01 / Narrow scope

One product line

No fit-out, no AV integration, no operations contracts. Everything we quote is something we manufacture.

02 / Standardised

Built from proven models

Most projects start from a unit we have already engineered, built and shipped — not from a blank page.

03 / Cost structure

No layers in the price

Structure, sheet metal, acrylic and control cabinets are made in-house. There is no subcontractor margin inside our quotation.

04 / Engineering depth

The third year matters

Wear parts, access panels, spare-part kits and control logic are decided at design stage, for the day after opening.

Who we build for

Museums first —
and the rooms beside them.

Same factory, same models, different constraints: an atrium is judged from twenty metres away, a children's floor from sixty centimetres up. Public art, school labs and visitor centres come off the same benches.

Science & technology museumsWhole floors or a single unit — from thirty exhibits to three hundred. Children's discovery centresIndoor playground, soft play and hands-on stations for ages 3–10. Planetariums & space theatresAstronomy interactives that work beside a dome, not inside it. Schools & community science roomsCompact, robust sets for one classroom or a district centre. Public art & atrium commissionsKinetic sculpture, light works and outdoor-rated pieces for public space. Visitor centres & showroomsBrand-led interactives and product explainers, one unit at a time.

Models you can order
without a design phase.

These are finished products with fixed dimensions, a fixed control package and a known lead time. Order one unit or forty; the specification does not change.

We also run
the shop.

Most factories only ever quote by email. We keep a public storefront: PopSciCat, our own English online store, where 2,000+ standard models are listed with prices in USD — sign in free, put a shortlist in the cart, download the configuration lists, and only then talk to us about customising it.

A published price is a promise: it means we are willing to be compared on the same model, by anyone, before a single email is exchanged. The store also sells in single units — the same minimum as our factory quotes.

04 / Where they go

Exhibits are chosen
hall by hall.

A museum is not one brief. The atrium needs a landmark, the children's floor needs height, the mechanics hall needs weight. We organise the catalogue the same way your floor plan is organised.

Atrium & Signature exhibition hall
01 / 12 exhibit types

Atrium & Signature

The first thing a visitor sees. Scale, movement and light above head height.

 Children's Discovery exhibition hall
02 / 12 exhibit types

Children's Discovery

Low, soft, open-ended. Built for ages 3–10 and for the hundredth visit.

 Electricity & Magnetism exhibition hall
06 / 12 exhibit types

Electricity & Magnetism

Fields you can feel, current you can follow.

 Body, Brain & AI exhibition hall
14 / 12 exhibit types

Body, Brain & AI

Where biology meets computation: neurons, signals, decisions.

 Computing, Telecom & Media exhibition hall
15 / 12 exhibit types

Computing, Telecom & Media

 Low-Carbon Living exhibition hall
18 / 12 exhibit types

Low-Carbon Living

Energy, water, waste and the choices that add up.
All 20 hall types →
05 / Capabilities

Structure, sheet metal,
acrylic, control.

Four processes, one roof. A steel frame, its cladding, its transparent parts and its control cabinet never leave the building between design and crating.

That is why we can quote a single unit at a sensible price and still hold a delivery date: nothing waits in a queue at a third-party workshop.

See the process →
01

Structure

Welded steel and aluminium frames, designed for public use and powder-coated.

02

Sheet metal

CNC cutting, bending and forming for panels, housings and mechanisms.

03

Acrylic

Cutting, edge-polishing, thermoforming and bonding for covers and tunnels.

04

Control

Cabinet assembly, PLC and microcontroller programming, sensor integration.

06 / How it runs

Six steps, one team,
no handovers.

The same engineers who draw the exhibit answer the questions during installation. There is no account manager between you and the workshop.

01

Enquiry

Theme, floor plan, age range, budget band. A photo of the space is enough to start.

02

Selection & specification

Exhibit list with dimensions and power requirements, plus a layout proposal for your architect.

03

Quotation

Priced line by line against your list. Export packing and installation quoted separately.

04

Manufacturing

Built in our own factory. Every unit runs for a test cycle before it is crated.

05

Export & documents

Plywood cases, packing list, commercial invoice, certificate of origin, freight terms on request.

06

Installation

Engineers on site for positioning, commissioning and staff handover, or remote supervision.

07 / Delivered

Our largest single supply so far — 200+ interactive exhibits for an 18,000 m² science centre in East Java, installed and commissioned in two months. Floor area and quantity are the client's published figures.

08 / Why buyers stay

We are paid for exhibits,
not for square metres.

A turnkey contractor earns on the whole package — ceiling, lighting, graphics, exhibits. We earn only on the exhibits, so our incentive is to make each unit better and cheaper, not to grow the package.

That is also why we are comfortable with single-unit orders and with being a subcontractor to another contractor. Both are normal work for us.
