The origins of Interhides
Ongart Thumrongsakunvong is a Thai manufacturing executive associated with Interhides. The company’s history identifies him and Chutima Busayaphoka as the founders of Inter-Hides Leather in 1992, initially engaged in leather tanning.
His disclosed educational record includes Assumption Sriracha School and director training through the Thai Institute of Directors. It does not establish a university degree, and none is invented here. The early company name, the later listed business and his executive titles should be kept separate when tracing the career.
From leather production to vehicle interiors
The corporate milestone record describes a change from upholstery leather towards the automotive industry. Today, Interhides’ product page sets out a service range covering raw materials, engineering, manufacturing and sewing, with design processes such as perforation, quilting and embossing.
This is the materials and interior-trim side of vehicle production, not engine manufacture. Leather preparation, a cut component and a finished seat-cover service also represent different production steps. The company’s description explains the business Ongart helped develop without proving its promotional claim to serve every major automaker.
Keeping leadership titles in their dates
A 2022 AGM invitation identified Ongart with chairman and managing-director responsibilities. The later director directory lists him as vice chairman and managing director, while naming a different board chairman. The two records should not be flattened into one unchanged current title.
His role therefore spans entrepreneurship and continuing management within a listed supplier. A historic shareholding figure, especially one including a spouse’s holdings, is not interchangeable with personal income or net worth. The biography focuses on documented work rather than inferred financial rankings or private family arrangements.
Changing markets and the EV question
At the 2024 shareholder meeting, executives discussed diversification, higher costs and opportunities as manufacturers established production in Thailand. The discussion noted that leather seats and trim were not engine components, an important distinction when considering electric vehicles.
The meeting’s growth expectations were management views, not completed sales results. Remarks made by director Wasin Thumrongsakunvong are not reassigned to Ongart as personal quotations. The record illustrates the commercial questions facing his company without assuming that every EV investment automatically creates orders for its products.
