Custom Cover Glass Solutions for OEM Display Projects
WM Cover Glass solutions develop custom glass components for electronic display and touchscreen projects. We work from customer drawings, samples or technical specifications to define the glass material, dimensions, cutouts, edge finish and required surface treatments.
Depending on the application, processing options include CNC machining, chemical strengthening or thermal tempering, silk-screen printing, AR/AG/AF coatings and adhesive lamination. We can also coordinate project-specific inspection requirements before shipment.
For a quotation, send us your drawing or sample details, target thickness, estimated quantity and application. Our team can review the requirements and identify the information needed to move the project forward.
Custom Cover Glass Solutions for Your Display Project
A touch screen cover glass part is often defined by more than its outside dimensions. A drawing may specify mounting holes, edge conditions, printed borders, coating areas or adhesive placement. These details affect how the glass fits into the finished product and which processing steps are required.
WM Cover Glass solutions works with OEM customers on glass components for electronic displays, touchscreens and control interfaces. Projects can be reviewed against drawings, physical samples or technical specifications, with material selection and processing requirements considered together.
The objective is to establish a practical manufacturing specification before production: what glass is needed, which features must be machined, what surface treatment is required, and how the finished part will be inspected.
What Needs to Be Confirmed Before Manufacturing?
Before a custom cover glass solutions order moves into production, several details should be agreed upon:
- Drawing and dimensions: Overall size, thickness, tolerances, hole positions, slots and cutouts.
- Glass material: Soda-lime, aluminosilicate or a specified specialty glass, depending on the design and performance requirements.
- Edge and surface condition: Ground, polished or beveled edges, along with any specified surface finish.
- Printing and coatings: Graphic layout, ink colors, printed borders, AR/AG/AF treatment and the required coating surfaces.
- Assembly requirements: Adhesive type, bonding area, protective film and any alignment requirements.
- Inspection criteria: Dimensional tolerances, appearance standards and any specified optical or coating tests.
If a drawing or sample is available, it is helpful to include it with the initial inquiry. If some specifications have not yet been finalized, identify the open items so they can be reviewed before production.
Custom Cover Glass Designed Around Your Specifications
Custom cover glass solutions projects often involve more than selecting a glass size. Mounting holes, cutouts, edge finishes, printed areas and surface treatments all affect how the component fits into the final product.
WM Cover Glass Solutions work from customer drawings, samples or technical specifications to define the required glass dimensions and processing steps. Depending on the project, details may include:
- Dimensions and geometry: Overall size, thickness, tolerances, holes, slots and irregular shapes.
- Edge requirements: Ground, polished or beveled edges, according to the design.
- Surface appearance: Printed borders, logos, symbols and specified coating areas.
- Assembly requirements: Adhesive placement, bonding areas and alignment features.
Providing these details at the quotation stage helps identify missing specifications and potential manufacturing constraints before production begins.
Cover Glass Solutions Processing and Finishing Options
The required processing sequence depends on the glass material, part geometry and final application. A custom cover glass component may require several operations, from cutting and machining to strengthening, printing and surface treatment.
Adhesive Lamination
Pressure-sensitive adhesive or other specified bonding materials can be considered according to the assembly design. Important details include adhesive type, thickness, bonding area and liner configuration.

Optical Surface Treatments
Different coatings address different surface requirements on ag ar af cover glass:
- Anti-Reflective (AR) Coating: Used to reduce surface reflections and improve display visibility under suitable lighting conditions.
- Anti-Glare (AG) Coating: Diffuses reflected light to help manage distracting reflections on display surfaces.
- Anti-Fingerprint (AF) Coating: Helps reduce visible fingerprints and makes routine surface cleaning easier.
The appropriate coating and surface configuration should be selected according to the optical, handling and cleaning requirements of the application.
Silk-Screen Printing
Glass printing can be used for borders, logos, symbols, labels and other specified graphics. Artwork, colors, printed areas and alignment requirements should be confirmed against the approved drawing or sample.
Chemical Strengthening and Thermal Tempering
The strengthening method depends on the glass composition, thickness, geometry and required performance.
- Chemical Strengthening: Ion exchange creates surface compressive stress and can be suitable for certain thin-glass applications.
- Thermal Tempering: Controlled heating and rapid cooling create a tempered glass structure with different strength and breakage characteristics.
These processes are not interchangeable in every application. Material compatibility and the required specifications should be reviewed before selecting a method.
Glass Materials for Custom Cover Glass Solutions
Material selection affects the achievable thickness, processing options, mechanical performance and project cost. The right choice depends on the application and the specifications the finished component must meet.
- Soda-Lime Glass: An option for projects where cost, general display requirements and processing needs must be balanced.
- Aluminosilicate Glass: Worth considering when the application calls for specific mechanical performance or a thin-glass design.
- Gorilla Glass: A branded glass option for projects that specify this material and its associated product requirements.
When requesting a quotation, specify the preferred glass type if known. If material selection is still open, provide the application, target thickness and required performance so suitable options can be evaluated.

Custom Cover Glass Quality Inspection
Inspection requirements should be defined according to the approved drawing and the intended application. Depending on the project, checks may cover dimensions, thickness, edge condition, holes and slots, surface appearance, printed graphics, coating requirements and specified optical properties.
Not every project requires the same inspection items. Agreeing on the applicable tolerances, appearance criteria and test requirements before production helps both parties evaluate the finished parts against the same specifications.
