Manufacturing

Full-process production, start to finish

Sheet metal forming, foaming, refrigeration assembly, performance testing and export packing are all carried out inside the 杭州炬卡电器有限公司 factory. That is what allows us to build customised cabinets and small batches without losing consistency.

Production workshop
The Equipment Base

Advanced machinery, controlled tolerances

The factory runs fully automatic laser cutting machines, punch presses and bending machines, an automatic dual-gun high-pressure foaming machine, a CACL high-precision dual-system filling machine and an INFICON high-sensitivity leak detector.

Reliable equipment matters more than it sounds. Cabinet squareness determines whether the door gasket seals; foam density determines whether the cabinet holds temperature overnight on a solar system; and filling accuracy determines how long the refrigeration system lasts.

  • Sheet metal: automatic laser cutting, punching and bending.
  • Foaming: dual-gun high-pressure machine, 65 mm and 110 mm insulation options.
  • Charging: CACL high-precision dual-system filling machine.
  • Leak testing: INFICON high-sensitivity detector, two checks per unit.
Production Stages

What happens at each step

Six stages take a coil of steel sheet to a packed, tested solar cabinet.

Sheet metal and mould work
1. Sheet metal and forming

Outer shell and inner liner are cut, punched and bent on automatic lines. Our shell is 0.4 mm and the liner 0.32 mm, thicker than the 0.35 mm and 0.26 mm used by most competing products.

High-pressure foaming
2. High-pressure foaming

Foaming runs on an automatic dual-gun high-pressure machine inside a room held at a constant 20–23 °C all year, which is what keeps insulation quality stable.

Condenser production
3. Condenser and evaporator

Wire-tube, multi-wire, shutter and roll-bond condensers are produced in-house. Tube diameter is 6.0 mm rather than the common 4.78 mm, with denser wires for better heat rejection.

Compressor assembly
4. Refrigeration assembly

Refrigeration system and control components come from dependable brands, confirmed by severe-condition testing in our own laboratory. All compressor motor windings are copper, and every controller uses a large aluminium housing.

Cooling fan and controller
5. Testing and charging

Both the condenser and evaporator sections are nitrogen-purged before any joint is made. Vacuum must reach 20 Pa or lower or the unit cannot be charged. Every unit is then leak-tested twice with the INFICON detector — unpowered and running.

Export packing and loading
6. Packing and loading

Cabinet paint, door alignment and accessories are checked against the order, then units are cartoned to the packing dimension listed in the catalogue and loaded to the 40HQ container plan.

Built Into the Cabinet

Details you can check on the sample

None of these are visible in a catalogue photograph. All of them are visible on a sample unit — and all of them are things buyers commonly find downgraded elsewhere.

On the door frame: the frame is made from a specially customised LG130 low-temperature material that resists cracking when the inside and outside of the cabinet sit at very different temperatures. On the lock: the lock hook is concealed rather than left exposed. On the compressor room: the compartment is entirely metal, with a metal side plate, rather than calcium-plastic board or cardboard.
Customisation

Individual specifications, small batches

Because every process is in-house, a customised order does not have to mean a container-load minimum.

Cabinet colour

Body colour and trim can be specified for your market or your own brand identity.

Handle style

A choice of handle and latch designs, including models using our concealed lock hook.

Panel design

Front panel print, light box and branding panel are all configurable.

Control type

Mechanical or electronic control, and single- or dual-temperature configurations.

Condenser position

External or built-in condenser, depending on cabinet size and the market's room layout.

Voltage and power

DC 12 V / 24 V for solar and battery, AC 220 V, or one of the four solar power architectures.

Insulation thickness

65 mm or 110 mm foam layers, matched to the ambient conditions of the destination market.

LED lighting

Interior LED corn lamp, rated for around ten years, optional on display models.
