VstrongTech is a Shenzhen-based industrial computer manufacturer that customizes I/O, power input, touchscreen, enclosure and hardware configuration for OEM equipment. We customize industrial panel PCs, fanless box PCs, industrial monitors and rugged tablets.
Most OEM requests are met by modifying a proven platform rather than designing from scratch. This keeps MOQ, lead time and certification risk manageable.
This guide covers three things:
- What can be customized in each area.
- How each change affects MOQ, lead time and validation.
- How to brief a supplier so the first sample is close to right.
Customization Matrix at a Glance
Effort and impact grow from top to bottom.
| Area | Typical options | MOQ impact | Lead-time impact | Validation needed |
|---|---|---|---|---|
| Software / BIOS | Boot logo, auto power-on, watchdog, OS image preload | None to low | Days | Functional test |
| Hardware configuration | CPU tier, RAM, storage, Wi-Fi/4G/5G, TPM | Low | Depends on part availability | Functional and thermal check |
| I/O | COM count and type, isolation, CAN, GPIO, extra LAN, M12 connectors | Low to medium | 1–3 weeks extra | I/O test, EMC check if wiring changes |
| Power input | Wide-range DC, 12/24V, ignition sensing, isolated input, terminal block | Medium | 1–3 weeks extra | Power and EMC retest may apply |
| Touchscreen and display | PCAP vs resistive, glove/water modes, cover glass, AG/AR, high brightness, optical bonding | Medium | Depends on panel supply | Optical and touch test |
| Enclosure | Logo/color, mounting type, front IP rating, stainless steel, new size | Medium to high, NRE for new tooling | 4–8+ weeks for new tooling | IP test (IEC 60529), vibration |
1. I/O Customization
I/O is the most common OEM request, because machines connect to PLCs, sensors, scanners and legacy serial devices.
- Serial ports. You can specify the number of COM ports and set each to RS-232, RS-422 or RS-485. Add isolation if the machine has motor drives or long cable runs.
- Field and vehicle interfaces. Options include CAN bus, isolated digital I/O (GPIO/DIO), and additional Gigabit LAN ports. LAN ports can be separated for machine network and plant network.
- Connectors. Lockable USB, M12 connectors for vibration and wash-down areas, and rear terminal blocks instead of DB9 or DC jacks.
- Port placement. Ports can be moved to the bottom or side to suit your cabinet layout.
What to tell the supplier: the device on each port, cable length, and whether ground loops or electrical noise have caused problems before.
2. Power Input Customization
Power input decides whether the PC survives in your machine. Common changes:
- Input range. Fixed 12V or 24V DC, or wide-range DC (e.g., 9–36V) for equipment with unstable supply.
- Ignition sensing and delayed shutdown. Required for vehicle and forklift installations, so the PC shuts down cleanly when the engine stops.
- Isolated power input and surge/reverse-polarity protection. For machines sharing a supply with motors or solenoids.
- Connector type. A lockable terminal block or connector instead of a barrel jack.
Changing the power stage can affect EMC and safety results. Ask whether existing test reports still cover the modified unit. Our pre-order checklist for buying industrial computers from China explains which documents to request.
3. Touchscreen and Display Customization
- Projected capacitive (PCAP) or resistive. PCAP gives multi-touch and a glass surface that is easy to clean. Resistive works with thick gloves and a stylus, and resists false touches from water and oil.
- PCAP tuning. Glove mode and water rejection for wash-down and outdoor use.
- Cover glass. Thickness, anti-glare (AG) and anti-reflection (AR) coating, and chemically strengthened glass.
- High-brightness panels and optical bonding. For sunlight-readable outdoor equipment such as EV chargers and kiosks. Optical bonding reduces reflection and prevents condensation behind the glass.
- Size and aspect ratio. Your choice is limited to sizes the panel makers produce in industrial grade. A supplier should tell you which sizes have long-term availability.
4. Enclosure Customization
- Branding. Your logo, color (RAL code) and front label. This is low cost and low MOQ.
- Mounting. Panel mount, VESA, embedded (open-frame) or yoke mount, matched to your machine’s cut-out.
- Front sealing. An IP65/IP66-rated front bezel for panel-mount installations. For wash-down lines, a fully sealed stainless steel housing. See what the IP65, IP67 and IP69K tests actually check.
- New housing design. A new size or form factor requires tooling (mold or sheet-metal dies), an NRE fee and a longer sample cycle.
Important: An IP rating applies to a specific enclosure build. Adding a cable gland, port or vent means the modified enclosure should be retested.
5. Hardware Configuration
- Processor platform. Choose a CPU tier that fits your software load and thermal budget. For equipment that will sell for many years, prefer Intel embedded/IoT roadmap SKUs, which carry extended availability.
- Memory and storage. RAM capacity, industrial-grade SSD, and a second drive for data logging.
- Wireless. Wi-Fi, Bluetooth, 4G/5G and GPS modules. Note that adding radios brings radio-equipment compliance into scope (RED in the EU).
- Expansion. Mini-PCIe or M.2 slots, and PCIe slots in larger panel PCs, for capture cards, fieldbus cards or AI accelerators.
- Security. TPM 2.0, and port disabling in BIOS.
6. Software and BIOS
These are often the cheapest changes with the biggest effect on the end user:
- Custom boot logo.
- Auto power-on after power loss.
- Hardware watchdog.
- USB and port locking.
- Preloaded OS image with your application.
Ask the supplier to keep your BIOS version under change control. A silent BIOS update can break a validated machine.
The OEM Customization Process
- Requirements brief. Include a drawing or photos of the installation, an I/O list, power supply details, environment (temperature, ingress, vibration) and annual volume.
- Feasibility and quote. The supplier confirms what can be done on an existing platform, the MOQ and NRE, and an itemized lead time.
- Engineering sample. You test it inside your machine.
- Revision and golden sample. Changes are documented, and the approved unit is signed off by both sides.
- Pilot run. A small batch confirms production consistency before volume.
- Mass production. BOM and BIOS are frozen, and any later change requires written notice.
How to Tell Whether a Supplier Can Really Customize
- They ask questions back. A capable supplier asks about cable length, grounding, ambient temperature and mounting depth. A reseller just says yes.
- They separate configure-to-order from engineering work. They give different MOQ, NRE and timelines for each.
- They show test evidence for modified builds, not only catalog datasheets.
- They talk about long-term availability of the CPU and display before you ask.
FAQ
Can a China-based manufacturer customize I/O and power input for a small OEM order?
Yes. I/O and power-input changes on an existing platform are usually available at moderate MOQs. A new enclosure or custom mainboard typically requires higher volume or a one-time NRE fee.
What is the cheapest way to customize an industrial panel PC?
Branding and BIOS changes cost least: logo, color, boot screen, auto power-on and watchdog. Configuration changes such as RAM, storage and wireless modules come next. Physical changes to I/O, power, display and enclosure cost the most.
Does customization affect CE certification?
It can. Changes to the power stage, mainboard or wireless modules may require updated EMC, safety or radio testing. Cosmetic changes like logo and color normally do not.
Can I get a sample of a customized industrial PC before ordering in volume?
Yes. A customized project should always include an engineering sample tested in your equipment. The approved unit becomes the golden sample that production must match.
Which products can VstrongTech customize?
VstrongTech customizes industrial panel PCs, HMI touch PCs, fanless box PCs, industrial monitors and rugged tablets for OEM equipment makers and system integrators.
