• Substantially increase the lifespan
• Reduce the risk of scratch during maintenance
• Improve the releasing capability
• Reduce the usage of lubrication oil during the operation
All above benefits can be achieved with careful selection of coating and recipe. Nanofilm has been specialized in this area and to spearhead the development since the company established. We have demonstrated and be the benchmark standard for different precision molding industries namely.

Forming Tools and Dies
Forming Tools and Dies
High temperature deposition (>400C) is not allowed in precision forming die. The dimension of WC will alter slightly. Ti based coatings is not good candidate for this application.
Ti based coatings have high friction coefficient (0.5) as compared to DLC (0.1). Low friction will ensure the operation generates lesser heat and ensure smoother lead surface after forming.
DLC is non sticky to the lead’s surface which typically is plated with Ni alloys. Minimum residue is observed on the DLC coated die compared to TiN coated or uncoated die

Nanofilm’s L series system is designed to deposit a layer of ta-C film with precise control of coating thickness and film properties. The machine is the industrial standard for the glass lens insert coating to prolong the lifespan and to reduce the sticking issue during the glass lens production. All major digital camera makers are using the L series system to in their production to improve the production efficiency and to reduce the cost of glass lens fabrication. The benefits of the ta-C deposited with this machine are namely:
• Able to withstand high temperature (up to 900ºC) under
control ambient
• Ready recipe for most kind of glass materials and lens
diameters (from pick-up to SLR lens)
• Deposit on the large lens for SLR camera (>50mm) with
low particle count
• Deposit on the aspherical lens will excellent uniformity
(<5%)
• Coat on large angle lens (~70º) with good uniformity
(<30%)
The machine is equipped with the following configuration to cater for the most stringent requirement
• Two chambers system to eliminate the environment
contaminate
• Fully automated system enabling the pumping, transfer,
ion beam cleaning, FCVA deposition and venting
• Database to log the necessary process and production
record
• Safety features enabling the safety of the operators
• Designed and built for clean room environment
In additional to the glass lens application, the machine is suitable for the CD/VCD/DVD/HD-DVD/BD mold coating. The coating is able to improve the lifespan of the mold (on the stepper side) up to 4 millions shots. The coating is also suitable to use for plastic and rubber injection mold coating
