linkage mechanism are recessed into the door panel, making the hinge invisible when the cabinet door is closed (concealed installation).<br \/>Transmission and Rotation Axis: The hinge cup connects to the hinge arm, which is the fulcrum for the door panel&#8217;s rotation.<br \/>Standard Door Panels (18mm &#8211; 20mm): Select a standard 35mm cup diameter + 11.5mm cup depth.<br \/>Thin Door Panels (14mm &#8211; 16mm): Select a 35mm shallow cup (8.5mm deep) or a 26mm mini cup to prevent drilling through the decorative panel.<br \/>Thick door panels (\u226525mm): Select 40mm large cup or special

Here is how we deliver value to your business:<\/p><p>Unbiased Market Curation (More Choices &amp; Better Prices): Unlike single factories that only praise their own capacity, or traditional trading companies restricted by personal connection networks, we evaluate the entire Chinese manufacturing landscape. We benchmark and source from multiple verified factories to secure the most competitive pricing and the exact product specifications you need.<\/p><p>100% Transparency (Your &#8220;Brain&#8221; in China): We never hide behind the veil of being a &#8220;fake manufacturer.&#8221; We act as your transparent, in-country purchasing department. You always know exactly who is producing your goods, how much they cost, and what the real lead times are.<\/p><p>Uncompromised Quality &amp; Risk Mitigation: Our business is built on long-term partnerships, not one-off high-profit transactions. We perform strict, independent quality control from your perspective before shipment, protecting you from post-purchase defects and communication breakdowns.<\/p><p>Streamlined Communication &amp; Service: No more dealing with slow, production-centric factory service. We provide a single, highly responsive point of contact that manages the entire supply chain\u2014from negotiation and quality checks to shipping logistics\u2014saving you time and reducing headaches.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t<details id=\"e-n-accordion-item-1822\" class=\"e-n-accordion-item\" >\n\t\t\t\t<summary class=\"e-n-accordion-item-title\" data-accordion-index=\"3\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-1822\" >\n\t\t\t\t\t<span class='e-n-accordion-item-title-header'><div class=\"e-n-accordion-item-title-text\"> What types of industrial automation instruments products can you purchase from Instrava? <\/div><\/span>\n\t\t\t\t\t\t\t\t\t<\/summary>\n\t\t\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-1822\" class=\"elementor-element elementor-element-4b79f34 e-con-full e-flex e-con e-child\" data-id=\"4b79f34\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-617efcb elementor-widget elementor-widget-text-editor\" data-id=\"617efcb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Level Gauges, Flowmeters, Transmitters, Level Switches, Edge Gateways, APL Switches, Liquid Analytical Instruments, Optical Analytical Instruments, Gas Detectors, Energy Monitoring &amp; Control Systems, Power Transformers, Cold Heading Machine, New Energy-Energy Storage, Hybrid Inverters, Inverter Generator, Industrial Machinery, furniture hardware(cabinet hinges\u200b) etc.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t<details id=\"e-n-accordion-item-1823\" class=\"e-n-accordion-item\" >\n\t\t\t\t<summary class=\"e-n-accordion-item-title\" data-accordion-index=\"4\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-1823\" >\n\t\t\t\t\t<span class='e-n-accordion-item-title-header'><div class=\"e-n-accordion-item-title-text\"> How to ensure the reliability of the purchased products? <\/div><\/span>\n\t\t\t\t\t\t\t\t\t<\/summary>\n\t\t\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-1823\" class=\"elementor-element elementor-element-acb26a8 e-con-full e-flex e-con e-child\" data-id=\"acb26a8\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-2d5bf5e elementor-widget elementor-widget-text-editor\" data-id=\"2d5bf5e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Our customer-centric philosophy prioritizes their procurement needs.<\/p><p>1.
