Trusted by Cookware Manufacturers Worldwide
"The precision of the large hole on these G-type covers is impeccable. It drastically reduced our assembly reject rate for our new smart multi-cooker line. Their capacity to deliver high-volume orders consistently is top-tier."
"We struggled to find a supplier who could guarantee edge smoothness around the sensor hole without compromising the glass's temper. This supplier completely solved our thermal cracking issue."
"Excellent communication and rigid adherence to our tight tolerances. Customizing the 304 stainless rim profile alongside the specialized glass hole was seamless. Highly recommended B2B partner."
Wholesale & OEM FAQ
Q: What is the Minimum Order Quantity (MOQ) for custom-sized hole glass lids?
A: For wholesale and B2B orders, our standard MOQ typically starts at 1,000 units per specification to ensure cost-efficiency in automated production.
Q: What is the standard lead time for a container-load (20ft/40ft) shipment?
A: The lead time for a standard 20ft/40ft container is approximately 25 to 35 days, depending on custom rim requirements and production scheduling.
Q: Do your G-type glass lids meet international food-grade safety certifications?
A: Yes, all our tempered glass components comply with FDA, LFGB, and other major international food contact safety regulations.
Q: How do you ensure the structural integrity of the glass around the "big hole" under high-temperature stress?
A: We utilize advanced thermal tempering processes and precision edge-smoothing techniques around the bored hole to eliminate stress concentrations, ensuring high thermal shock resistance.
Q: What is the precision tolerance for the hole diameter and positioning for automated assembly lines?
A: Our CNC-guided boring machinery maintains strict tolerances (typically ±0.5mm) for both hole diameter and positioning, guaranteeing seamless integration into your automated cookware assembly lines.
Q: Can the stainless steel rim width and grade be customized along with the G-type profile?
A: Absolutely. We offer complete customization for the stainless steel rim, including grades like 201 or 304, varying widths, and specific venting integrations to match your exact OEM specifications.
