Why Work With Us?

Every Solution Starts With Your Problems

Price Too High, Budget Under Pressure

You don’t have to pay extra for the same specifications. We help you reduce costs while fully meeting your standards.

Only Quoting, No Product Expertise

You don’t just want a price—you want someone who truly understands your needs. We clarify your requirements before quoting, drawing on years of experience.

Original Models Discontinued, Hard to Find Replacements

Obsolete models don’t mean you have to scrap your equipment. We custom-make replacement parts for discontinued models.

Lead Time Too Long, Project Falling Behind

Every week counts—delays are not an option. Our standard production lead time is just 45 days.

Big Brands Ignore Small Orders Or Minor Tweaks

Small orders and minor adjustments matter, too. We handle custom tweaks and low-volume runs with fast turnaround.

Worried About Unreliable Quality From China Factory

You need proven reliability, not just paper specs. All our products come with real factory test reports.

frequently asked questions

About ordering

→ 30 Days Sample | 45 Days Mass Production

The minimum order quantity (MOQ) is 10 units.

A setup charge typically covers additional expenses related to customizing standard components or performing special operations requested by customers. These charges depend entirely on the complexity of the modifications, are design-specific, and usually apply to each order separately.

The Low Volume Charge (LVC) helps to clearly identify these fixed costs, ensuring transparency when ordering smaller quantities. This charge accounts for the higher proportion of fixed manufacturing expenses inherent in low-volume production runs.

Potentiometer Performance

We manufacture Conductive plastic ourselves and strictly control the processing flow to ensure the electrical performance of the resistor components.

Yes, we can provide mass production of replacement-type potentiometers and other related components.

Yes, we can customize and produce products such as angle sensors and linear sensors.
