In-Plant Courses

对于许多客户来说,厂内注塑培训是进行员工培训的理想方法,因为这可以培养员工使用自己的机器和模具的能力,最为重要的是可以根据员工的特定需求灵活调整培训,与RJG区域团队合作制定相应的实施计划。建立良好的培训计划可以让公司衡量成功并在出现问题时随机应变。同时培训大量员工也是一种管理培训计划的高成本效益方法,并且公司有机会在各部门中培训一“组”人员,从而更好的支持长期成功。另一个益处是, RJG培训师/顾问能够集中关注解决特定的注塑成型出现的问题。

RJG培训与其他同类培训活动的不同之处在于,我们的顾问有能力去解决问题,他们从塑料材料的角度出发,通过针对具体技能、业界公认的实际操作培训来传授自己的知识和经验,这与传统的培训视角有很大不同。如果培训实施得当,您的技术团队将能够顺利开展合作,以正确诊断根本原因,以及预防和解决每年导致注塑制造商损失数十万美元的各种问题。RJG顾问所能提供的,是在线和基于CD材料的培训或一个培训师“单人秀”不能比拟的。我们经过验证的培训方法同时受到数据和投资回报驱动。

Material Handling

Learn the proper skills for material handling.

This course walks students through the proper techniques for material handling and troubleshooting. The course explains the ins and outs of raw material management, what to consider when choosing materials, what to watch out for in product labeling, and what to consider when determining dryer requirements. Emphasis will be on the main material considerations and how drying affects the process. The objective of this course is to reduce errors and inconsistencies in processing due to material handling issues.

Course Highlights:

Understanding Material Labels

  • Reading labels (trade name, common name, chemical makeup)
  • Understanding tech data sheets (drying time, temperature, and dew point)
  • Explaining tensile strength, specific gravity, etc.

Drying Basics

  • Types of dryers (compressed air, hot air, desiccant, pressurized)
  • Basic components and diagrams
  • Central vs. portable vs. press mounted
  • Temp, air flow, time
  • Moisture analyzers
  • Cleaning (common mistakes)
  • Banking temps – the good, bad & ugly

Material Storage

  • Closed containers
  • Contamination (mixing materials)
  • Cumulative dry times

Grinding Considerations

  • Low speed high torque vs. high speed (blades, screen, etc.)

Loading Options

  • Venture vs. vacuum vs. central (pipes, elbows, connections, cleaning, etc.)

Blending Advantages and Disadvantages

  • Types (gravimetric blender, auger, screw, tumbler, or shovel)
  • Regrind & Colorant

Hoses – Grounded vs. non-grounded wire

This course is offered exclusively as an in-plant course and is only available as an add-on day with the Injection Molding Essentials course.

Course length: 1 day

Class Pre-requisite: No previous training required

Successful Strategies for Tool Launch

Course Description

Detect mold design issues before they become an expensive problem!

This course is intended to show how part design and mold build interact with the process. It is intended to show how to get the right mold in the right machine. A great course for part and mold designers and tooling engineers.

By challenging both designs and molds early in systematic ways, weaknesses can be quickly defined and corrected before they become costly problems. Participants will also develop the tools to measure the mold, machine, and process capability interactions to determine the best recipe for successful tool launches.

Course Highlights

  • Basic part geometry related to processing concerns
  • Review part design complexities
  • Sizing of the mold for the right press, more than just tie bar spacing
  • How the mold design and build affects quality and total product costs
  • How molds can be tried out systematically to hit the quality bulls-eye
  • How plastic behaves as it travels through the stages of a process
  • Systematic troubleshooting to separate material, process, design, and mold problems
  • Why hot runner molds are fundamentally different
  • Cooling capabilities
模板匹配

课程说明

学员将了解如何记录现有工艺并使用计算、转换以及可能通过eDART™应用的模板法将现有工艺转移到另一台机器。我们将深入讨论如何根据塑料变量(包括必要时通过eDART使用图形数据)建立强健的记录和匹配工艺,这是转移模具最为精准的方法。本课程强调在排查工艺问题时考虑塑料变量的重要性。课程中安排了大量实验室实际操作环节,同时也留出了充分课堂时间来让学员了解核心的“系统成型”概念并提出自己的问题。

学员将学习如何检验已建立的对于工艺能力以及识别模具性能要求的工艺表。学员们还将学习如何评估实际的机器性能并且了解为作业选择最为合适的机器可遵循的规则。工艺匹配的目的在于使用塑料变量作为指导进行重复工艺匹配,而不是使用总会发生变化的机器变量。

机器变量也有可能导致某一模具无法从一台机器转移到另一台机器上去。机器测试有助于确定两台机器是否兼容。
