Process and Tooling Makeover with Productive PlasticsSaves Industrial Material Handling Manufacturer Time,
Cost, and Improves Quality Performance
Existing ProjectAlternate Vendor
Oct 2015
The DetailsProductive Plastics was approached by a major industrial materialhandling manufacturer that was looking for solutions on a part foran existing project, at the time being manufactured by anotherthermoforming vendor, which was experiencing significant deliveryschedule delays, poor quality performance, and inconsistent partdimensions.Delivery Delays
Poor QualityPart Defects
Part of the Productive Plastics product developmentcycle when taking on an existing project is to evaluate anumber of key existing factors such as the currentlyused tooling, process, trimming, and design to helppresent the most appropriate solution to our customer.
We understand that when a customer looks for a newvendor, it’s because the customer’s needs were notbeing met previously and we want to make sure that weprovide the solutions they are looking for.
In this case, Productive Plastics identified the existingelements on the left as key contributors to the deliveryschedule delays, poor quality performance, andinconsistent part dimensions plaguing this project.
Discovering the Root of the Problem
Existing ProjectContributors Negative Effects
Inadequate toolingconstruction withno temperaturecontrol
High part reject ratio,slow part cycle time
Part trimming via hand routing and drilling
Part dimensioninconsistency
Creating the Solution
After evaluating the process and tooling previouslyutilized for this project, our team of engineers,designers, and manufacturing experts at ProductivePlastics worked with this customer to upgrade to anadequate tooling design, utilize CNC trimmingtechnology, and take advantage of the high quality andextremely efficient manufacturing techniques availableat our facility.
New Aluminum Temp. Controlled Tooling
CNC Trimming
FAI (First Article Inspection) Quality Check
Lean Manufacturing Practices
Comparing the Results
SummaryUpgrading to a properly constructed tool with adequate temperature control was one of the largest changesto this project after it was received by Productive Plastics and there was a significant cost investment fromthe customer associated with this.
The benefits (see above) of this new and correctly designed tooling were a major factor in eliminating theproblems that were previously associated with the project and originally prompted the customer to seek usas a new vendor. This is not an uncommon occurrence in the thermoforming industry, where a vendor willpresent a customer with a quote for inadequate tooling construction either from a lack of knowledge or in anattempt to win business by offering a more appealing quote with a cheaper tooling cost.
