About the protective case

WINARM instrument and equipment cases are manufactured by HouLang inc.

All WINARM hard sided cases are manufactured at HouLang factory in GuangDong, China.

As of 2025, there are currently 5. distinct WINARM sizes available. We are always developing newdesigns so new sizes of transportable cases will be added every year.


The WINARM protective cases for your application should take into account the size of your components and allow for a laver of foam between 1 and 2 inches all around to adequately protect your equipment. Highly sensitive equipment should allow for more foam to allow for extra protection.

Changes in altitude and geographic location create a vacuum that effectively seals the waterproof case. WINARM's pressure valve can balance this air pressure difference. Under different pressure environments, we can manually adjust the pressure valve to achieve pressure balance. Micro-vents allow air to pass through while preventing water from entering. Our products with the pressure release system are able to create excellent diving watch cases.

WINARM rugged suitcases are available with or without protective foam. The optional high-density foam is multi-layered for easy customization. The multi-layer customizable liner includes a pre-scored removable layer. The liner consists of square foam that can be removed to accommodate the different sizes of the items in the case.

We can develop custom foam inserts for your application. Contact us to find out how we can help you.

WINARM equipment cases have been tested and cerftified by an independent laboratory for thefollowing specifications:
