Cutting delivery time to tool makers
By increasing the cutting speed of their Friggi 600 x 2,000 vertical bandsaw, Sorel Forge Co. has also increased the speed of delivery of cut steel blocks by a day or more. The company can cut blocks up to 24 inches thick, with close tolerances due to the saw’s blade deviation. They can make slices that are 0.5 inches thick and form blocks that are 10 inches to 24 inches thick. The Friggi vertical bandsaw can be programmed with up to 100 different speeds and feeds based on size and grade of material. Additionally, it can perform multiple cuts of various sizes from a single piece.

New hot sprue nozzle, valve gate sequencing controller
Osco, Inc. will display two new developments at Plast-Ex 2007, a new hot sprue nozzle and an improved valve gate sequencing controller.
The hot sprue nozzle, HSN MINI, is a very small hot sprue designed to fit into the unit die systems M-U-D and F-I-T-S. With an overall nozzle length of just 1.875 inches, it permits the use of hot sprues in small mold inserts. This size is also the most common size for unit die cavity inserts. And the company’s VGS valve gate sequencing controller has just been improved, to be smaller, quieter and more energy efficient, which saves money. It now uses 120 VAC. Its touch-screen monitor allows for mold storage and ease of use. It can be used to control either hydraulic or pneumatic valve gate systems, which don’t have to be an Osco valve gate. Additional features are standard time-based control with optional linear position as well as cavity pressure signalling.

Additive helps with mold release
Croda Canada will showcase four new developments in additives for the polymer industries: Incromold, Incromax, Crodamide and Atmer. Incromold is a range of internal mold-release additives. Added to polyolefin resins, they continuously help to release the part from the mold without having to stop the machine periodically and spray mold release onto the mold. Incromax is a range of mold release additives for PET, polystyrene and polycarbonates, and gives the same benefits as Incromold does. Crodamide is a range of slip and anti-block products for films. Atmer is a range of anti-static and anti-fog additives for films and injection-molded items.

CPSC offers two new virtual programs
The Canadian Plastics Sector Council (CPSC) has launched two new programs designed to assist both employers and employees in the plastics industry. The certification program is a web-based tool that allows workers to measure their skills against national occupational standards. An online self-assessment is reviewed by at least three peer evaluators to ensure that a candidate has met the industry standard. CPSC has also launched the Virtual Human Resource Department, which helps employers deal with issues in the increasingly complex field of human resources within the plastics sector. The system is filled with information that will help the small- to medium-sized business get answers to a variety of human-resource problems.
