COMPONENTS

Intelligent designs guarantee high quality output of rubber parts. Meeting productivity, safety, and quality expectations is essential to ensuring our customer’s complete satisfaction.

Injection Unit

Injection Unit

Designed for accuracy and easy maintenance, both Vertical and Horizontal Injection Units come equipped with FIFO or standard injection systems. Shot volume is injected against backpressure and metered via a high resolution linear scale. Temperatures are microprocessor controlled from the standard temperature controllers running through an external jacket at the plastification screw. This is independent from the injection shot chamber that is temperature regulated through concentric passages to provide uniform heat control. The plasticizing screw is a swing away design and the injection cylinder piston retracts clear from the chamber allowing fast cleans.

Hydraulic System

Hydraulic System

Designed for durability, efficiency and quiet operation, the hydraulic system features a direct drive tandem pump. Speed and pressure are controlled by proportional flow and pressure valves. Directional valves are mounted to the easy access monoblock manifold. A heat exchanger maintains hydraulic oil temperature via the main PLC. A reservoir float switch monitors for low oil levels and the 25 micron oil filter is electronically monitored for blockage. Standard "off-the-shelf" components are utilized wherever possible.

Control System

Control System

Engineered for accuracy and repeatability, the full-featured control system combines flexibility with ease of use. Assembled using standard commercially available components such as Allen Bradley PROSET featuring Expert Response Compensation, an adaptive learning, closed loop system that automatically compensates for material viscosity, hydraulic valve wear and mold wear. The results are high shot to shot repeatability and unparalleled profile execution stability resulting in low scrap rates.

Safety System

Safety System

Sherdil engineering adheres to the world's most stringent safety standards while improving productivity. Standard light curtains protect pinch points while allowing fast access to load and unload. Individually keyed limit switches with positive contacts are used extensively.

Clamp Unit

Clamp Unit

Robust design featuring flame hardened, thermally pre-stressed columns. The heavy sliding bolster uses split bronze bushings for easy replacement. Full hydraulic with prefill valving or hydraulic mechanical designs available, utilizing fast closing/opening cylinders. Speed and pressure are infinitely adjustable from the control panel.

Platens

Platens

Precise temperature control, even heat distribution and rapid heat up times are assured through the use of PID controlled electrical cartridge heaters with individual heat outputs depending on location within the platen. Close tolerance ground insulating board on the sides and under the platen minimizes heat-loss. Platens are precision ground and feature T-slots for mold placement.

DataTrak Systems

DataTrak Systems

A computerized central control system for the supervision of up to 32 Molding Presses. User-friendly Windows operation and database storage of all production parameters for each cycle. "Adjustment logger" discourages unnecessary set up adjustments.
