Model 2200-245-051 Tip-Seal dispense valve is for precision dispensing of low- to high-viscosity flowable materials. It is also used in high-speed stitching or repetitive on-off applications where short segments of material are deposited onto a surface.
 
The zero-cavity design helps dispense solvent-based, moisture-curing and stringy materials such as silicones or polyurethanes. Sealing at the tip prevents material from hardening in the nozzle, oozing or dripping. The valve opens and closes its material passage at the tip of the nozzle to precisely start and stop material flow.
 
Pneumatically actuated, the valve has a carbide tip, titanium-coated shaft, hardened seat and wear-resistant fluid seals to extend valve life. The stroke adjuster can set the needle opening to change material-flow rates and bead-profile sizes.
 
The valve’s precision dowel and screw holes allow easy and accurate mounting. The 0.125” orifice and short 0.32” tip length (8.1 mm) enables the valve to reach into parts and fixturing. Other orifices and tip lengths are available. Material is delivered to the valve by either a metering assembly or under regulated pressure from supply tanks or pumps.

ENVIRON provides web systems for managing WEEE compliance for business products, and the group has launched a new customer relationship module. 
 
Hosted on the company’s Website, the system enables companies to gain feedback from its customers on product satisfaction and after-sales service. Customers wishing to use the WEEE collection and recycling system are required to complete a marketing questionnaire which is emailed to the company.  As part of the questionnaire, customers are required to enter valid model numbers to use the system.
 
The WEEE web system:
Provides a single contract to manage producer registration, in-country recycling, and compliance reporting in all Member States;
Provides straightforward collection arrangements, which the company can communicate to business end-users through their own company website;
Offers a single corporate solution that can be expanded to cover other countries;
Includes the option to pass collection costs on to business end-users;
Provides flexibility and control of future WEEE recycling arrangements, enabling companies to ensure that recyclers continue to provide competitive rates for their services, and change recyclers in individual Member States to take advantage of new recycling technologies and techniques;
Demonstrates to customers that the company is compliant with the WEEE Directive and has addressed its environmental responsibilities.

SEFAR LDS is a laser technology stencil imaging machine for small format screen printing applications. With imaging capabilities between 1700 and 2400 dpi, it reportedly creates precision stencils that adhere to high quality standards, perfectly placed on each screen to ensure consistent color-to-color registration.
 
Available in two configurations: 1330 (max. screen size 15.5 x 17.5 in. – developed for the optical disc market) and 4060 (max. screen size 25.5 x 27.5 in.). Both systems are said to increase productivity (by removing several prepress steps from stencil making through on-press registration) and reduce costs by eliminating time and expenditures associated with conventional film imaging processes.
