Glass Drinkware Manufacturers

As an important utensil in daily life, glass drinkingware not only enhances the experience of drinking, but is also favored for its health and environmental protection characteristics. However, when choosing glass drinkingware, consumers are often full of doubts about the materials, manufacturing and quality control of glass drinkingware. As an industry leader, Yangzhou New Coordinate Household Articles Co., Ltd. has long been committed to the research and development and production of glass drinkingware, and its strict quality management system has set a benchmark for products.

Q: How does the production process of glass drinkingware ensure material safety and harmlessness to the environment?

A: Glass drinkingware is usually made of high borosilicate glass or soda-lime glass, which have excellent heat resistance and chemical stability to avoid reactions with drinks or release of harmful substances. The production process involves high-temperature melting, molding and cooling, among which temperature control and impurity removal are key. Yangzhou New Coordinate Household Articles Co., Ltd. strictly follows international standards in production, reduces heavy metal residues by optimizing melting parameters, and ensures that each product meets food-grade safety requirements. At the same time, the company emphasizes recyclability and sustainability, and glass materials can be 100% recycled and reused, reducing the environmental burden.

Q: How to achieve the heat resistance and impact resistance of glass drinkingware? Why are some products prone to cracks or breakage?

A: Heat resistance depends on the composition and annealing process of the glass - high borosilicate glass has a low expansion coefficient and can withstand rapid temperature changes without breaking; impact resistance is enhanced by a uniform molecular structure and thickened design. However, minor defects in the production process, such as uneven internal stress or surface microcracks, can significantly reduce durability. Yangzhou New Coordinate Household Articles Co., Ltd. has invested in advanced spectrometers and pressure testers to detect bubbles and cracks inside the glass in real time, and verify product strength through simulated impact tests. These measures ensure that the drinkingware remains intact when exposed to high temperatures or accidental falls, avoiding safety hazards for consumers.

Q: How can the beauty and transparency of glass drinkingware be kept consistent? Why are there bubbles or unevenness under light?

A: Transparency comes from the purity of the glass and the surface polishing process; impurities such as iron ions can cause yellowing or turbidity, while bubbles or unevenness come from smelting or mold defects. Bubble size greater than 0.5 mm will affect the optical effect and even become a breaking point. Yangzhou New Coordinate Household Articles Co., Ltd. uses a high-precision optical inspection system to scan and analyze each product to identify surface unevenness and tiny bubbles. Based on computer vision technology, the system can capture defects that are difficult to see with the naked eye, ensuring that the drinkingware is smooth, transparent and flawless. This process improves the visual quality of the product and makes glass drinkingware an elegant embellishment on the dining table.

Q: How does Yangzhou New Coordinate Household Articles Co., Ltd. improve the overall performance of glass drinkingware through quality management? What specific role does their inspection equipment play?
A: Quality management involves full process monitoring - from raw material screening to finished product inspection. Yangzhou New Coordinate Household Articles Co., Ltd. invested in a spectrometer to analyze the uniformity of glass composition, a pressure tester simulates daily use pressure to evaluate crack resistance, and an optical inspection system automatically scans surface defects. Working together, these tools can efficiently identify subtle problems such as bubbles and cracks, ensuring that the product is impeccable in terms of aesthetics and durability. For example, the spectrometer can detect heavy metal residues at the ppm level, while the pressure tester can simulate repeated force scenarios to prove the long-term stability of the drinkingware. This rigorous testing system means consumers don't have to worry about product life or health risks.

Q: What are some professional recommendations for cleaning and maintaining glass drinkingware? How to avoid water stains or scratches that affect the service life?
A: It is recommended to use a soft cloth and non-abrasive cleaners when cleaning, and avoid hard brushes or strong acid and alkali solutions to prevent surface scratches or corrosion. Water stains usually come from mineral deposits in hard water and can be removed by regular vinegar washing. Scratches weaken the glass structure and increase the risk of breakage. Yangzhou New Coordinate Household Articles Co., Ltd. focuses on surface hardening in production, and its products undergo a special coating process to enhance wear resistance. At the same time, the company uses an optical inspection system to ensure that there are no initial scratches before shipment, and provides professional maintenance guides to help users extend the life of drinkingware.
