1.How to get a quote？
Please tell us the specifications, pressure, temperature, and applicable medium (such as acid or alkali concentration) you require. Our professional engineers will match the most suitable product for you and provide you with the best price.
2.Does the company provide free samples? The company generally does not provide free samples, except for special needs, and the shipping fee must be provided by the other party.
3.How does the company ensure product quality?
Our company strictly implements ISO9001:2015 quality management system and glass-related standards, such as DIN7080, DIN7081, BS3463, JIS B8286, JIS B8211, JIS R3206 and other world's most stringent product standards. Our manufacturing and quality inspection engineers successfully control Surpassing the complexity of tolerances and using a variety of measuring equipment to ensure safety and accuracy, our glass sight glasses can meet the requirements of the world's top equipment manufacturers and various national guidelines.Our glass sight glasses are manufactured from strictly controlled raw materials and carefully smelted by experienced operating engineers, with high temperature resistance, high pressure resistance, excellent transparency and good chemical resistance.Our production engineers will inspect each piece of glass after every step of the production process to ensure that it meets the high parallelism, flatness and optimal surface roughness required by the customer. Through careful grinding and polishing, it is ensured that there are no scratches or burst edges, and the surface quality is almost perfect.Each of our glass sight glasses has undergone special high-temperature toughening treatment so that they can withstand the pressure encountered during various harsh working conditions. In the toughening facility, our customized control software can perform precise control. After gentle cooling treatment, the bending strength of the toughened glass is increased by at least 3 times. The glass sight glass can see complete multiple color sequence spots under polarized light, indicating that the glass has been well strengthened and the stress meets the load requirements.Each toughened glass sight glass is printed with its own code to ensure product traceability. Even if the user has used it for several years, he can still check the basic factory information. Our engineers require high-quality materials to make high-quality glass sight glasses, so our glass incorporates the best performance requirements for sight glasses: no impurities, no water marks and no bubbles, thus ensuring efficient optical performance. Even with thicker safety glass, you can still have good visual effects.Our company's professional thermal toughening technology gives glass good thermal shock resistance. Therefore, our products are particularly safe and durable!
4.How do you deliver the goods?
We can choose suitable sea freight, air freight, and international express delivery according to the customer's needs, and select the most economical and fastest logistics delivery method based on the actual situation of the goods.
5.Can the company customize the specifications we want? Our company can customize various safety glass sight glasses with high temperature resistance, high pressure resistance, chemical resistance, and excellent thermal shock resistance according to customer needs, and issue EN10204-3.1 or 3.2 factory quality certificates, or according to customer needs Invite certification agencies such as TUV to come and witness the test.Our company can also provide OEM and ODM brands for users, making it convenient for agents from various countries to set up their own glass brands.
