It identifies as a professional technical supplier and supports customization from samples and designs, but does not provide 3D software design, ODM, SDK, or branded OEM services, and reported no new products in the past year. Export activity is substantial, with 10 years of export experience and exports representing 90% of total sales. Service support includes debugging and maintenance in South America, although there are no overseas branches, agents, warehouses, or showrooms. Quality oversight is limited to one inspector, and finished-product inspections have instructions but no written records.
