Miller-Leaman Inc. now targets its liquid Thompson strainers to the plastics industry. In plastics, the strainers filter cooling water. The patented design features a conical-shaped filter element.
A limited surface area on the upper part of the screen causes the particulate to be accelerated downward to the reservoir. The material is flushed out through a port.
Thompson strainers are available with inlet/outlet sizes of 2, 3, 4, 6, 8 and 10 inches.

Zygo offers standard hot-runner system
Zygo Mould Ltd. of Toronto now makes standard hot-runner systems to complement its existing mold manufacturing capability.
Zygo delivers fully assembled and tested hot-runner systems consisting of the manifold, manifold plates, nozzle tips, housings, heaters and thermocouples.
The systems can be used in molds ranging from 2-48 cavities. Zygo recently introduced a hot runner for a 2-by-24 cavity stack mold for closure production, with an inside center gate for superior part cosmetics.
Zygo offers hot-runner systems in standard hot-tip style or air-actuated, double-acting valve gates.
Zygo said a licensing agreement with Husky Injection Molding Systems Ltd. of Bolton, Ontario, gives Zygo the right to make and sell products using Husky's valve-gate technology.

Hunkar targets OEMs with monitoring line
Injection molding companies that cannot afford to buy a broad-based computer-integrated-manufacturing system have a new option: Hunkar Laboratories Inc.'s Source line.
Hunkar said it would cost about $20,000, plus the cost of a personal computer, to equip a 10-machine plant.
The Source program includes machine monitoring modules, called Class-Meter, a background central computer program and an Expert Program that helps make decisions.
It can manage up to 32 machines.
According to the Cincinnati company, the machine terminal is the most expensive part of a CIM system.
It also requires data to be input by machine operators. But the Class-Meter, a small module mounted inside the machine's control cabinet, gets around that by fully automating data collection. It collects information and sends it to a central file server.
No training of floor personnel is required.

Tradesco Mold touts hot-runner innovation
Using technology developed through its four-level stack molds, Tradesco Mold Ltd. has developed a stand-alone hot-runner system for use in two-cavity, back-to-back stack molds.
Rexdale, Ontario-based Trades-co said the system is best-suited for molding large, shallow-draw parts such as trays, industrial lids and houseware items.
In the past, the company said, the design of conventional sprue bars prevented two-cavity stack molding of large parts.
The firm transfers the plastic around the molded product. The design features a valveless melt transfer mechanism that passes the plastic across the mold parting line without drooling.
By eliminating the sprue bar, stack molds now can be made for quick product changes, according to Tradesco.

Kona power units provides versatility
Kona Corp. has introduced Hydraulic Power units for use with Kona's Hydraulic Valve Gate hot-runner systems.
The power unit is self-contained, with a reservoir, electric motor, pump, control valves and programmable logic controller.
The units are available with 1-12 zones. Larger versions are available. Each control zone has a two-stage timer that controls a corresponding valve.
Kona, of Gloucester, Mass., presets the operating system pressure based on customer requirements.
