- Proper material handling techniques
- Processing characteristics of virgin and regrind

Material Drying Technology

Routsis Training’s two Material Drying Technology online courses provide participants with a better understanding of how different polymers are best dried and prepared for reliable processing. These courses show participants how proper plastics material handling and drying is critical to produce a consistent product and process. Course One reviews polymer basics, as well as both hygroscopic and non-hygroscopic polymers – to better convey the importance of properly drying water-sensitive materials.

Material Drying Technology, Course 1

- Polymer Basics
- Hygroscopic vs. Non-Hygroscopic Polymers
- Hydrolysis
- Purposes of Drying
- Dewpoint

- Dewpoint Sensors
- Drying Procedures

Material Drying Technology, Course 2

- Hot Air Dryers
- Compressed Air Dryers
- Desiccant Dryers
- Vacuum Dyers
- Calculating Material Consumption
- Calculating Residence Time
- Calculating Dryer Capacity

Injection Molding Hydraulics

These online training courses demonstrate the importance of hydraulics – and the proper maintenance of hydraulic components – in the injection molding process. Machine operators will learn ways to reduce wear on hydraulic components, while more advanced employees concentrate on hydraulic print reading and theory.

- Basic hydraulic theory
- The role of hydraulics in injection molding
- The function and purpose of hydraulic components
- Recognition of hydraulic symbols
- Directional valves and flow controls
- Hydraulic pumps and motors
- Proportional valves and servo valves
- Hydraulic fluid management

2 Online Courses (2-4 hours + Study Guides)

Process Control Systems

This training program details process control systems and is designed to help molders make more educated choices. Process Control Systems is a must for any facility which employs (or plans to employ) closed loop process control.

Open loop vs. closed loop process control
How process control reduces variation
Closed loop controllers
Proper use of process control

Blueprint Reading
The six programs in our online blueprint reading training course develop workers’ abilities to accurately locate and interpret dimensions on engineering drawings. These training programs are based on ANSI standards and incorporate input from a broad industrial cross-section.

The primary audience is production and inspection personnel, supervisors, group leaders, set-up personnel, and anyone who wishes to read engineering drawings.

Course 1: Introduction to Engineering Drawings

- Explains the purpose of an engineering drawing
- Distinguish between a detail drawing and an assembly drawing
- Interpret the drawing scale
- Explains the purpose of dimensions and tolerances

Course 2: Multiview Drawings

- The six principal views of a third-angle projection
- Identify the ISO symbols for third-angle and first-angle projections
- Auxiliary views, partial views, and enlarged views
- Determine which line takes precedence over another

Course 3: Sectional Views

- Determine which portion of the part is shown in section
- Explain the purpose of section lines and identify the ways in which they are used
- Identify and interpret the common drafting conventions applied to sectional views

Course 4: Dimensions and Tolerances, Part 1

- Identify the size and/or location for a given part feature
- Correctly calculate the tolerance specified for a given part feature

Course 5: Dimensions and Tolerances, Part 2

- Locate and interpret dimensions specified by chain, baseline and direct dimensioning methods
- Identify a datum feature and explain its purpose
- Explain how maximum material condition (MMC) and least material condition (LMC) apply to internal and external features
- Calculate allowance
- Identify a surface finish specification

Course 6: Part Feature Specifications

- Identifies twelve of the most common part features on a drawing
- How to correctly interpret part specifications

5S SkillSet™ Series

The 5S System SkillSet™ Series is a unique learning experience that combines detailed, step-by-step online instruction with practical hands-on labs and worksheets.

Each of the five course/worksheet combinations focuses on developing important Lean Manufacturing related skills that translate directly to any production or workplace environment.

This exclusive training approach allows companies to perform the same type of classroom learning found in popular seminars in the comfort of their own production environment. Your employees will develop effective 5S Skills so they can contribute directly to and help maintain your Lean Manufacturing efforts.

Each unique training course is a blend of the following components:

Your technicians understand the goal of each 5S SkillSet™

Technicians learn specifically how each 5S SkillSet™ applies

Items are detailed to ensure techs have the tools they need to succeed

Each step is demonstrated so your techs can proceed with confidence

Contains all the information your techs need to succeed with each 5S SkillSet™

What’s Covered in the 5S Skillset™ Series?

The 5S SkillSet™ labs teach a sound approach to Lean Manufacturing. With 5 distinct skills being taught, your technicians can quickly learn how to apply proven Lean Manufacturing techniques to the everyday production environment.

Your processors and technicians will receive hours of online SkillSet™ instruction and hands-on labs to confidently develop the following abilities:

Step 1: Sorting

In the 5S System, the Sorting step’s goal is to eliminate all unnecessary items from the immediate workplace. This is done by sorting the workplace to determine what to keep, what to toss, and what to store. This helps prevent clutter from interfering with everyday production activities.

Step 2: Straightening

At the end of the Straightening step, everything in the workplace is neatly organized; resulting in a more convenient and more efficient workplace.

Step 3: Sweeping
In the Sweeping step, the best method for cleaning each selected area in the workplace is determined. A reasonable cleaning schedule should also be determined to ensure the workplace remains efficient, clean and organized.

Step 4: Standardizing

The goal of the Standardizing step is to achieve consistency. A similar appearance and layout should be applied to all workstations whenever possible. This step is often performed after a similar workplace or area within the plant has already been straightened.

Step 5: Sustaining

The purpose of the Sustaining step is maintenance. This is achieved by a review of the workplace and the existing Sorting and Straightening documentation – to ensure the workplace is efficient and up-to-date. This helps identify necessary materials or equipment that have been added to the workplace but have not yet been incorporated into the 5S documentation.
