In this section, we detail Wilmad’s extensive manufacturing capabilities. We have nearly a 60 year record of providing the best, state-of-the-art glass and quartz products. We continue to be the number one recognized name in the market for customer commitment and quality engineered products of the highest tolerances with strict quality control; the cornerstone of our operations. Only Wilmad provides a large dedicated staff with a full range of capabilities and a superior Quality Control and Assurance program. These levels of inspection standards ensure your Wilmad parts are the highest quality in the market.

MANUFACTURING CAPABILITIES Ultra precision heat and vacuum shrinking of glass including borosilicate, quartz, lead and Suprasil forms the core of Wilmad’s manufacturing operations.

Tubing of various diameters up to 7" is shrunk on precision stainless steel mandrels providing extremely tight tolerances. We have both vertical and horizontal shrinking machines for virtually any size tube in lengths up to 54".

The grinding processes both concentric (where both O.D. and wall thickness is precisely controlled) and centerless (where the O.D. is controlled) can be performed to the same precision tolerances as our I.D. work. Finishing can include polishing to optical tolerances as well as beveling, chamfering, ultrasonic drilling and wet saw cutting.

In our custom fabrication shop our skilled glassblowers have many years of experience in shaping almost anything either free hand or on lathes.

Facilities are available for vacuum silvering, forming glass-to-metal seals and manufacturing vacuum tube electronic feedthroughs. We offer the talent, know how and equipment to complete any job to set specifications.

QUALITY CONTROL Wilmad’s is ISO certified and has a stringent quality control program that begins with inspection of incoming material and follows through every step of the manufacturing process. Visual inspection by skilled workers during production ensures good quality. For some items microscopic inspection may be required to minimize inclusions and imperfections in the finished product.

To ensure tolerances are met, Wilmad’s QC inspectors use NIST calibrated micrometers, air gauges and other precision measurement equipment. Where required, items are also leak checked using our mass spectrometer.

ENGINEERING SERVICES Wilmad glass engineers are available for consultation on any project that requires special glass or quartzware; this includes following your precision part all the way through the manufacturing process. From conceptual phase through final QC our staff ensures that a Wilmad part is a quality part. Fax or e-mail your specifications and we will be happy to quote to your requirements and in many cases suggest a possible “in stock” alternative.

CUSTOM PRODUCTS The following sections of this brochure detail many of the standard Wilmad products and product lines. Also shown are the capabilities to produce almost any glass or quartz product that one can imagine. Even if you don’t see a specific item in this catalog that can meet your requirements, contact us for a feasibility consultation. If a part can be manufactured, chances are Wilmad can do it.

WILMAD’S MANUFACTURING AND ENGINEERING CAPABILITIES

SECTION 3

STANDARD PRODUCT LINES This catalog is designed to keep our customers advised of the sizes and shapes of precision bore tubing and specialty items that we manufacture. Over the years, we have provided many products in virtually all types of glass and quartz.

We are the premier manufacturer of many types of products which we supply as a finished part or as a subassembly to companies all over the world.

The following descriptions and photographs depict what we consider to be standard products; i.e., items that we have produced by the thousands over many years. Since no two customers have exactly the same requirements for a given part, we would like to offer these standard product lines as a possible starting point for your particular design.

The skill and precision demonstrated by these illustrations are what you can expect from Wilmad as “standard.�

PRECISION BORE TUBING

Precision bore tubing is produced by heat shrinking commercial tubing on precision mandrels.

This process, combined with appropriate finishing, is what we at Wilmad do best. In many cases, this tubing is the final product but can be just the starting point for many other products.

Wilmad precision bore tubing is available in glass and quartz in almost unlimited sizes, shapes and wall thicknesses.

Precision bore (PB) tubing by Wilmad is presented in Sections 5, 6, 7 and 8. Specifically, PB capillary tubes are presented in Section 5; PB quartz tubing in Section 7; and square PB tubing in Section 8.

The tubing tables in these sections detail the tooling and mandrels currently available. If you require a size, shape or material not listed, please submit exact specifications for availability and pricing.

Our engineers are available to assist you during the product development process and technical issues.

Our flexibility and years of experience are your assurance that we can supply precision bore glass and quartz tubing of practically any size, length, and shape to the most stringent dimensional tolerances.

STANDARD PRODUCT LINES

FLOWMETER TUBES

Wilmad produces a wide range of flowmeter tubes for both liquid and gas metering. We can provide the blank precision tube or a completely calibrated assembly depending on your requirements. We have made flowmeter tubes several inches to 3 feet long with I.D.’s ranging from a few millimeters to several inches. Tubes can be fluted or ribbed on the I.D. to provide a guide for the float.

Wilmad’s success with this product line can be attributed to our skill in heat shrinking glass on precision mandrels. A rigorous quality control program with step-by-step inspections, numerous flow measurement checks, and flow calibration assures that each Wilmad flowmeter tube and rotameter meet required specifications.

SYRINGE BARRELS Syringe barrels are another precision assembly that Wilmad provides for a number of clients. Syringes are analytical devices that require ultra-precise manufacturing and strict control skills. Syringes like these are used to accurately measure minute volumes of a liquid in automated pipeting, diluting or titration apparatus.

SECTION 3

STANDARD PRODUCT LINES Wilmad PB Tubing, when matched to electrical components, meets the exacting requirements of the Electronic Industry.

Wilmad tubing and assemblies are proving our hard-earned reputation for quality in hundreds of applications and practically every electronic use‌ our craft people maintain rigid glassware tolerances to help keep these devices in service longer.

Our electronic glassware is available in the various specialty glasses. We also work in synthetic and natural quartz and other glasses manufactured by Schott, Corning and Kimble-Chase. Electronic engineers have found that glass, when worked with precision and held to tolerances equally as stringent as those applicable in metal, can be successfully and profitably used as components in electronic assemblies and subassemblies. When they are needed, we can effectively produce the metal-to-glass seals necessary in many electronic applications.

VARIABLE HIGH VOLTAGE CAPACITORS Specialized high voltage capacitors are manufactured for D.O.D. communications systems. These items illustrate many of our specialty talents. The envelope is precision bore quartz. The assembly requires quartz-to-metal seals as well as several machining and fabrication steps.

Rigid quality control guarantees that the final product meets MIL-SPEC tolerances and performance criteria.

WAVE GUIDES

These glass tubes will eventually become traveling wave tubes, components in a magnetron.

In this application, precision is critical to maintain the uniformity of the microwave currents which travel through the wave guides. Wilmad prepares the finest quality glass wave guides available anywhere.

TUBES ENVELOPES

These are envelopes for camera tubes such as iconoscopes, image orthicons, and vidicons.

Today, the most common application is in vidicon tubes, a device which relies on the phenomenon of photoconductivity to produce an electronic signal from an image of light or other radiation.

Wilmad precision tubing is the most reliable product in these sensitive devices.

GLASS TO METAL SEALS

The art of sealing glass to metal involves a thorough knowledge not only of glass, but of the linear coefficients of expansion of metals as well. The samples shown are good examples of efficient glass-to-metal seals. We offer tungsten, stainless steel and platinum.

At Wilmad, we specialize in the expansion match seal in which the fusion joints between glass and metal carry linear coefficients of expansion which are identical, or nearly so.

Our experience has been that the most effective seals are those which utilize nickel-cobalt-iron alloy such as Kovar.

If you require glass-to-metal seals in your operations, our engineers will be glad to discuss the subject in detail and quote on your requirements.

SQUARE AND RECTANGULAR TUBING Wilmad offers a wide range of square and rectangular tubing manufactured in glass and quartz. Certain sizes are available in precision grade as shown in Section 8 of this catalog. High quality tubes are also available as defined in Section 9. These listed products are normally in stock for fast delivery. Wilmad can supply almost any dimension or length of these products, so if the size you need is not listed, contact our sales staff with your exact requirements. Our engineers will present a proposal to meet your requirements.

PRECISION BORE QUARTZ TUBING

Wilmad also produces ultra-precision, uniform bore tubing in quartz including natural and synthetic. In most cases, we can hold the same tolerances as we do for Pyrex, Duran or KG-33 glass, particularly for I.D.s less than 1”. O.D.s can be ground concentrically or can be centerless ground and polished. We can hold the wall tolerance to ±0.001” or less in most sizes listed here.

Precision quartz tubing is also available in square and rectangular shapes, and square tubing is produced in sizes ranging from 3mm x 6” long up to 1 ½” x 12” long as specified in Section 8 of this catalog. Many other sizes and shapes of quartz tubing are also manufactured.

Please refer to Section 9 of this catalog for specifics.

Precision, high-purity, square tubing manufactured of clear fused quartz is frequently available from stock. Should your application demand purity better than that offered by clear fused quartz or if it is to be used for transmission in the UV to 200 nanometers, we can supply it in non-fluorescent synthetic Suprasil. If you require any of the listed sizes finished as cells, boats, or trays, please call and discuss your needs.

The sizes listed are available in various wall weights in clear fused quartz; ranging from 0.9mm - 1.75mm. In Suprasil we normally supply one wall weight of 0.9mm.

SPECIALTY BOROSILICATE & QUARTZ PRODUCTS MICRO SLIDES, MICRO CELLS AND CAPILLARIES Micro slides are precision rectangular glass capillary tubes with open ends and are used for microscopic inspection of liquid samples. Capillary action instantly collects the sample and the micro slide maintains a precision optical path length. Thin flat glass walls minimize evaporation.

Cover glass is not required and issues associated with the hanging drop technique are eliminated.

Micro cells are precision square glass capillary tubes for viewing microscopic objects in two optical planes at right angles. Micro slides and Micro cells are made from borosilicate glass.

DEFINITIONS

SPECIFICATIONS

CONCENTRICITY . . . A measure of the lack of uniformity of the wall-thickness of the tube, this tolerance can be thought of as the degree to which the cylinders defined by the inner and outer surfaces of the tube parallel and overlap.

Determined using an Indicating Gauge, this tolerance is reported as a deviation (w) or Total Indicator Reading (T.I.R.), i.e. the absolute variation in wall thickness at the ends of a tube rotated through 360°.

TOLERANCES . . . Our guaranteed tolerance limits are your assurance that our precision bore glass tubing will perform satisfactorily in even the most demanding applications.

I.D. tolerances vary somewhat depending on the I.D. of the tubing. However, depending on your particular requirements, we can supply PB tubing to the most demanding specifications. Nor is the I.D. the only tubing feature covered by our precise manufacturing procedure.

We control straightness, length, I.D., O.D., concentricity, finish, etc. with the same precision.

Method of specifying concentricity on drawings:

NOTE: Should you require tolerances more stringent than those listed above, don’t hesitate to call us.

STRAIGHTNESS . . . Straightness of the elements of a precision bore tube is a condition which no element deviates from a straight line.

Method of specifying straightness of elements:

WALL THICKNESS . . . The generally accepted method of referring to wall thickness in precision bore Tubing is by the terms Standard, Medium and Heavy. If it is important to your requirements that you know the actual dimensions of the wall thicknesses; our glass engineers will be happy to provide you with the necessary information.

LENGTHS . . . Although we have tooling for many lengths and sizes of PB tubing, it is important that we keep mentioning the need to order the shortest lengths available from the tooling on hand. The smaller lengths are easier to ship and we may be able to ship from stock.

MATERIALS . . . Generally our PB tubing is supplied in Pyrex Brand, Duran or KG-33 glass. However, we also work with various types of glasses. We also use synthetic or natural quartz, and can provide glass tubing for matched metal-to-glass seals.

CAMBER . . . A measure of the lack of straightness of a tube, this tolerance is determined by gauging the deflection at the middle of a tube held at the ends and rotated through 360º. Recorded as a deviation (±) or Total Indicator Reading (T.I.R.).

TIR . . . This is the Total Indicator Reading...or the maximum dial variation from the datum or reference point when measurements of the I.D., O.D., wall thickness, camber, etc. of a precision bore tube are taken.

ENGINEERING DATA

SECTION 10

ENGINEERING DATA PRODUCT FINISH . . . Based on your requirements, we can modify our precision bore tubing in end finish or outside surface. We can cut the ends square or at any angle.

End finished include simple crack-off, wet wheel cut, fine ground, fire polished, belt or felt polished. External finishes include both rough and fine ground and varying degrees of polish. A surface profilometer is available for accurately quantifying surface finishes.

CONFIGURATIONS . . . Wilmad PB tubing is available in round, square, or rectangular shapes in standard, medium, or heavy walls. However, we can make it in practically any shape . . . oval, hexagonal, tapered, and fluted . . . or other special shapes which meet your requirements.

TUBING CLASSIFICATIONS STANDARD TUBING . . . Standard tubing, as received from major manufacturers such as Corning, Kimble, Schott, and Kavalier has dimensional tolerances of w 0.3% depending on O.D. size. This type of tubing material is usually unsuited for precision parts but is used as the starting material for other classifications of tubing detailed in the links listed below.

36

REDRAWN TUBING . . . Redrawn tubing is produced by reheating standard or select material and re-extruding the softened material to rework the O.D., I.D., or shape to tighter tolerances. In many engineering applications, this material is sufficient and typically tolerances are from 5 to 10 times better than standard tubing.

PRECISION BORE TUBING . . . Precision bore (or PB) tubing, as Wilmad’s principal product, is manufactured to our industry’s strictest tolerances. The process of creating a piece of PB tubing involves the heating and softening of a standard tube over a precision mandrel. The glass is heated to the proper temperature and a vacuum is applied to the annular space between the tube and the mandrel. The final product is formed as the glass is softened and pulled over the mandrel. Each mandrel is carefully machined and polished to exact O.D. based on the difference in coefficient of expansion and contraction of the mandrel and the glass or quartz tubing utilized. Our stock of mandrels is extensive as listed in this catalog, and custom sized mandrels can be produced for virtually any I.D., shape or length.

ORDERING INFORMATION Wilmad PB Tubing is not priced in this catalog. Since every piece of Wilmad PB tubing and every assembly and subassembly made from it is custom manufactured to your specifications, it is not practical to prepare a price list in advance. Therefore, to receive a quotation, it is necessary to either write, e-mail, fax, or call customer service. Our glass engineers will review your needs and quote a price and delivery time. If your requirements are complex, please submit a drawing or sketch of the glassware you require showing all dimensions and tolerances.
