Injection molding is a process for manufacturing plastic products, also known as plastic injection molding. It is to inject molten plastic into a mold and form a product of the desired shape and size after cooling and solidification.

Mainly, granular or powdery raw materials are added to the silo of the injection molding machine. After being heated and melted, they become fluid. When the screw or piston rod of the injection molding machine moves, they enter the mold through the nozzle and the pouring system of the die-casting mold. The concave mold is shaped in the concave mold of the mold. After the product is completely solidified, the mold is opened and the finished product is taken out.

1. Our laminates used are carefully selected after evaluating more than 30++ kinds of variants.

2. Every piece of glass will have laminates to protect the surface.

3. A fixed qty will be packed and sealed in a plastic bag.

4. Followed by a fixed number of bags will then be packed in a small wooden box (not all glass makers are willing to invest in wooden box, most will use carton boxes)

5. Finally all the wooden boxes are then packed in a wooden crate.

6. Last but not least, KANOU will also invest in a tilt watch label (i.e “TiltWatch Plus”) in every wooden crate such that we can identify if the wooden crate is mishandled during freight.

Hardened and chemically strengthened glass are both types of safety or enhanced glass, but they differ in processing, characteristics, and testing methods. Here’s how you can distinguish between them:

🔥 1. Heat-Tempered (Hardened) Glass

Also known as thermally toughened glass, this is produced by heating the glass to ~620°C and rapidly cooling it to create surface compression.

Identification Methods:

• 🟦 Polarized Light Test: View the glass under polarized light—you’ll see strain patterns or colored stress halos, a hallmark of heat treatment.

• 💥 Breakage Behavior: When shattered, it breaks into small blunt particles (dice-like chunks), reducing injury risk.

• 🔧 Edge Hardness: Usually has a slightly rounded or polished edge due to thermal stress considerations.

• 🧪 Heat Soak Test Optional: For critical applications, a heat soak test is done to avoid spontaneous breakage from nickel sulfide inclusions.

🧪 2. Chemically Strengthened Glass

This type is ion-exchanged in a molten salt bath (usually KNO₃), replacing smaller ions with larger ones to create surface compression.

Identification Methods:

• 👁️ No visible stress pattern under polarized light—looks like regular glass.

• 💥 Breakage Behavior: Shatters into sharp shards, unlike tempered glass. It’s stronger, but not safety glass by break pattern.

• 📏 Higher Edge Strength & Flexibility: Chemically strengthened glass can be thinner and more scratch-resistant—ideal for cover glass and displays.

• 🔍 Surface Hardness Test: Often has higher scratch resistance than thermally tempered glass.

The 3As we are referring to are; Anti-Glare, Anti-Reflective & Anti-Fingerprint, or in short, we term it as AG, AR & AF.

Find out more above the applications of AG, AR & AF  in our KANOU Academy!

Gray glass is an ideal material to achieve a complete black effect on a vast landscape encompassing the touch or display module.

The common thicknesses of gray glass ranges from 0.7mm to 6.0mm, or even thicker. However, due to quality & stability issues, not all gray glass are suitable to be used as a cover glass, especially on touchscreen display / module.

Through our stringent testing & evaluations, we have ascertained the below thicknesses in production to be reliable:

1.8mm, 2.1mm, 3.0mm, 4.0mm

The answer is no.

The characteristics of color and light transmittance in gray glass are dictated by the inherent properties of the material. The transmittance levels for various thicknesses of gray glass in use today are established & fixed.  

Read up my blog for more info.

Can!

The surface of gray glass can be treated with etched AG or sprayed AG, which can effectively prevent glare and maintain a high-quality appearance.

Can!

The gray glass following the application of AF treatment exhibits not only an effective anti-fingerprint property but also offers a smoother and more comfortable tactile experience. Its use is highly recommended.

Not recommended!

Due to the properties of gray glass, AR treatment has a minimal impact on enhancing transmittance and thus AR has negligible impact.

Yes, but not recommended!

The application of white printing results in minimal visible impact from the front, leading to reduced practicality.

For printing purposes, we suggest the following solution:

Border color: A black border is advisable and can be adjusted based on specific requirements.

LOGO or other designs: We recommend using silver or semi-transparent black, as this option provides both subtlety and clarity. Alternatively, you may opt not to print.

Certainly, it is possible to obtain glass without undergoing chemical hardening for the purpose of trial fitting. However, it is important to be aware that the process of chemical hardening will result in a slight reduction in the dimensions of the glass. Therefore, the decision should be based on the level of precision required for your specific application.  

Throwing the glass is not a valid method to evaluate its impact resistance.
Chemically hardened glass is engineered for enhanced strength and surface durability, but like all glass, it has physical limits. To accurately assess its impact performance, standardized testing must be used.

⚠️ Key Points to Understand:

• Uncontrolled Drops = Unpredictable Results
  Throwing or dropping the glass by hand introduces inconsistent force, angle, and contact points, which can easily exceed its design limits—especially if it lands on a corner or sharp edge.

• Proper Testing Uses Steel Ball Drop Method
  The industry-standard method to evaluate impact resistance is the Steel Ball Drop Test. This involves:

  • A specified ball weight (e.g., 500g)

  • Dropped from a controlled height (e.g., 1.2 meters)

  • Onto a supported glass sample under test conditions
    This ensures repeatability, consistency, and objective measurement of durability.

• Application-Specific Tuning
  Our chemically strengthened glass is designed for normal use conditions, not uncontrolled impact.

Silkscreen peeling under UV exposure is often a result of substandard or non-UV-resistant ink.
If your current supplier’s ink fails under sunlight, especially in outdoor or high-exposure environments, it’s time to switch to a solution designed for durability.

✅ How KANOU Solves This:

• 🛡️ Anti-UV Ink by Default
  At KANOU, we use UV-resistant inks for all applications where exposure to sunlight or UV sources is expected.

• 🧪 Proven Ink Durability (Seiko GV3)
  We have proactively trialed and tested Seiko’s GV3 ink, a high-performance option rated to withstand up to 1300 hours of UV exposure—ensuring long-term print adhesion and appearance stability.

• 🖨️ Optimized Printing Process
  Our silk-screen printing is paired with controlled curing and surface preparation steps that further enhance ink bonding and durability, even in harsh environments.

If you’re facing silkscreen failure, we recommend:

1. Evaluating the current ink’s UV rating and cure process.

2. Switching to anti-UV ink solutions like those used by KANOU.

3. Requesting a sample or accelerated UV test report from us for validation.
