  • Finishing | Gillinder Glass

    FINISHING Gillinder Glass recognizes that after glass is molded and annealed, there is often a requirement for additional operations to perfect the customers’ products. Some glass manufacturers outsource these functions. However, Gillinder Glass has chosen to create its own, fully equipped, in-house, Finishing Department which allows us to carefully control quality at all stages of production and reduces transportation costs. ​ Our customers benefit from better quality and lower prices. Some of the feature equipment and functions of the department include: DCM Rotary Table and Lapmaster Grinders to smooth and flatten Sand Blasters to create diffusion, masking or slip resistance Horizontal, Circular, and Robotic Cutting Saws to create halves and other unique products Up Shock and Down Shock Equipment to test resistance to thermal shock Finishing Ovens to fine tune color, harden coatings, remove temper or re-anneal products Glass Painting Booth to mask areas, soften light hotpots (particularly from LEDs), or mask areas

  • Vapor Proof Globes

    Gillinder Glass produces a broad variety of glass products manufactured to the most rigid specifications to meet the tough demands of industrial work environment and harsh and hazardous conditions. Depending on the use, hazardous conditions may require glass to be abrasion resistant, thermal shock resistant, liquid resistant, impact resistant, vapor or dust resistant, or explosion resistance to avoid shattering from an internal explosion, particularly important in environments with combustible fumes. Vapor proof glass resists the influx of vapors and gas particles and is generally also liquid resistant. Gillinder Glass is a key supplier in the harsh and hazardous industries with products intended for environments needing vapor tight globes and fixtures with a corrosion and vapor proof aluminum cage. There are several types of vapor proof and waterproof ratings, including IP65, IP66, and IP67, which measure a products water resistance. An IP rating is composed of two numbers. The first number describing the products intrusion protection, or how much it withstands particles entering, which is based on a 0-6 scale. The second number measures the resistance to liquid on a 0-9 scale. These vapor proof globes also offer intrusion protection which is calculated using a system to rate safeguard against dust, particles, or solid objects of certain sizes. These are to ensure any ingress will not damage or impede the performance of internal components with full protection against dust and other particulates, including a vacuum seal, tested against continuous airflow. Gillinder Glass’ clear or colored tempered vapor proof glass is often used for ceiling, pendant, or wall mounted fixtures. A tempered soda-lime glass is generally used and can be produced with multiple finishes in a variety of colors. These “jelly jar” globes are also offered on and include the following open stock options: Gillinder can also manufacture custom sizes, colors, and finishes, such as white enamel (inside), sandblasting, plastic coating, smooth, and inside ribs. Common colors include: amber, aviation blue, opolo, red C, rs green, and traffic green. The chromaticity specifications, measured with CIE A, are as follows: Gillinder’s in-house engineering team precisely test vapor proof glass to confirm chromaticity requirements as well as performing impact and thermal shock resistance tests when needed. As these globes are often used for harsh outdoor locations waterproof requirements also may apply. --- Press Contact: Jackie Conklin- Marketing Specialist: For other inquiries, please call us at 845-856-5375 or email References: “The Comprehensive Guide to IP Ratings.” The Comprehensive Guide To IP Ratings | RS Components,

  • Mold Making- the Cornerstone of Pressed Glass

    In 1865 Gillinder Glass was established, and they opened a glass pressing factory in Pittsburgh, Pennsylvania. This was only forty years after John P. Bakewell invented the first commercial glass-pressing machine. Blackwell’s invention “quickly led to the mass production of glassware and greatly reduced its cost, leading to glassware being available for everyday use.* Today, Gillinder Glass still hand presses every piece of glass they manufacture. Advances in technology and greater customer demand has allowed Gillinder to start utilizing automated equipment for glass pressing and maximizing efficiencies. Glass pieces are generally made by pouring the molten glass into a mold and having a “plunger” pressed into the iron base. Almost all Gillinder’s molds are made from ductile iron, but some may require an A-2 tool steel or stainless steel may be used. Today, as an ISO 9001:2015 certified company, Gillinder’s Port Jervis factory is held to high standards of manufacturing quality and the in-house mold shop is no exception. Gillinder’s mold shop can collaborate with customers in designing new custom molds or refurbishing existing ones. Gillinder Glass has the capability to manufacture with customer’s existing hand pressed molds. Machine pressed molds can be used by making adjustments to be compatible with current equipment. Mold Shop supervisor, Lewis Still, explains, “Molds that run constantly usually need nothing more than a simple polishing, but sometimes they do need repair work. Average life span on mold equipment is about 5 years. After that, the tooling will start to develop what we call “fire cracks” which are stress fractures in the material from constantly being hot and cold.” Molds are housed in a special atmospherically controlled storage area and maintained in pristine condition after each use to ensure consistent production of the highest quality glass. Gillinder also has the ability to do prototyping and programing. In addition to working with almost all current software systems, the mold shop is equipped with: · Fadal Computer Controlled Vertical Milling Center 3016L · Computer Controlled Bridgeport Horizontal Lathe · Bridgeport Series 2 Vertical Milling Machine · LeBlond Horizontal Lathe · TUR 63 Lathe · Welding and Braising Shop (including gas spray welding) Gillinder has created molds for an array of products including headlights, traffic lights, dog food bowls, kitchenware, and even dental cuspidors. In the Spring of 2022, to further expand the Mold Shop’s capabilities, Gillinder is acquiring an additional CNC milling machine. The CNC milling machine precisely cuts molds from various design software to meet customer’s expectations in design and specification.
