Using SkillBuilder, valuable molding techniques are learned that translate to the production floor, making your production personnel more knowledgeable and more productive. Employees learn how to mold without tying up valuable machine time or damaging expensive equipment and tools.
Detailed SkillBuilder lab lesson descriptions Lesson 1 - Optimizing Melt Temperature Molding an Amorphous Material. Molding a cell phone cover in polystyrene, an amorphous material, the goal of this lesson is to create and maintain a melt temperature of 430°F. The available molding machine controls are the barrel heaters, screw rpm and the backpressure.Lesson 2 - Optimizing Melt Temperature Molding a Crystalline Material. Molding a cell phone cover in polypropylene, a crystalline material, the goal of this lesson is to create and maintain a melt temperature of 400°F. The available molding machine controls are the barrel heaters, screw rpm and the backpressure.Lesson 3 - Optimizing Fill Time to achieve the Fastest Fill Possible. The goal in this lesson is to fill the mold as fast as possible while still molding a good part. In general, good molding practice dictates
6
that the mold should be filled as fast as is practical. The plastic type is ABS and the available machine controls are the clamp tonnage, the fill rates and the holding pressure.Lesson 4 - Optimizing Part Dimensions Molding an Amorphous Material. Part dimensions are often critical in injection molding. This lesson teaches some techniques for tightly controlling part dimensions while molding an amorphous plastic like polycarbonate. Available machine controls are the mold temperature; fill rates and the holding pressure.Lesson 5 - Optimizing Part Dimensions Molding a Crystalline Material. Crystalline materials like polypropylene can be more difficult to keep to tight dimensions. This lesson teaches some techniques for tightly controlling part dimensions while molding a crystalline like polypropylene. Available machine controls are the mold temperature; fill rates and the holding pressure.Lesson 6 - Optimizing Part Weight to Achieve Minimum Plastic Usage. Reducing part weight to the minimum that makes a good part saves money by using less make a good part. Molding a bracket in polystyrene, the student will have the holding material. In this lesson molding techniques are explored that reduce plastic usage, but still pressure and the mold temperature as available machine controls. Lesson 7 - Optimizing Mold and Melt Temperature to achieve the most Efficient Cycle Time. Achieving the lowest possible cycle time can often be the difference between making and losing money on a molding job. Understanding energy balance is important. The less heat you put in the plastic the less you have to take out. Molding a cover in polyethylene the student has the barrel heaters, screw rpm, backpressure, mold temperature and cooling time controls available.

Injection Molded Part Problems and Solutions
Injection Molded Part Problems and Solutions is an eleven program that discusses eleven common molding problems and solutions to solve those problems. Topics covered include Voids, Sink Marks, Short Shots, Flash, Weld lines, Splay, Jetting, Burn Marks, Warp, Cracking, and Dimensional Control. This program is recommended for set-up personnel, foremen, process engineers, production supervisors and molding managers.
11
Detailed Lesson Descriptions for Injection Molded Part Problems and Solutions
Voids – Small holes in thick sections caused by plastic shrinkage.Sink Marks – Small depressions in molded part surfaces opposite thick sections, caused by internal stresses as the plastic cools.Short Shots – Undersized molded parts due to incomplete cavity filling from too little plastic, poor venting, mold or melt temperature problems, faulty part or mold design.Flash – Thin ribbon of excess plastic formed when plastic is forced between parting lines in the mold. Harmful to the mold and requires trimming operation for removal.Weld lines (Knit Lines) – Lines where plastic streams meet during mold filling, causing unsightly appearance and structural weakness.Splay (Silver Streaks) – Surface defect that occurs when gas bubbles are dragged along the plastic surface as it fills a cavity.Jetting – Surface defect caused when a jet of resin “shoots” through the gate and cools as a long string of plastic inside the cavity.Burn Marks – Burned plastic edge caused by plastic igniting in the cavity and the air in the cavity cannot escape and overheats.Warp – Molded part distortions from uneven stresses in the part caused by faulty molding conditions inside the cavities.Cracks and Part Breakage - Weak molded parts susceptible to cracking and breaking, as a result of incorrect molding conditions that can cause five different types of cracking problems.Controlling Molded Part Dimensions – Off-spec parts caused by dimensional changes throughout the part, in specific areas or directionally.
Specific SkillBuilder Lesson Descriptions For Injection Molded Part Problems and Solutions
The SkillBuilder lessons that accompany our "Injection Molding Problems and Solutions" CD training are designed to take the student from the classroom to the production floor. Using our state of the art molding machine simulation software, employee's can actually run a molding machine to improve their problem solving skills. The combination of IMPP&S with Skillbuilder machine simulation lessons provides approximately approximately18 hours of training.
The Problems and Solutions lessons teach the user the multiple causes and multiple solutions to six common molding problems. Users adjust machine controls and mold parts, guided by feedback from the simulator, to become expert molding problem solvers.
SkillBuilder provides the student with an opportunity to practice molding in a realistic environment without creating machine downtime.
Lesson 1 - Solving a Burn mark Problem. Burn marks on a molded part are caused by trapped air in the cavity. If the air in the cavity isn't adequately vented as the plastic fill the cavity it will be compressed, heated and ignite, charring the plastic. This SkillBuilder lesson guides the participant through some of the available molding techniques that will help eliminate a burn mark on a molded part. SkillBuilder allows experimentation with solving burn mark problems that would be impossible or excessively expensive using your parts and your molding machines.Lesson 2 - Molding to Precise Dimensional Tolerances. Controlling part dimensions can be a complicated molding problems because so many molding variables affect dimensions. Some of the primary influences affecting the final dimensions of the molded parts are the mold temperature, holding pressure and fill rates. This SkillBuilder lesson conducts experiments using those machine controls, which affect final part dimensions to lead the participant to a greater understanding of precisely controlling part dimensions. SkillBuilder allows experimentation that would be impossible or overly time consuming using an actual molding machine.Lesson 3. Controlling Flash on a Molded Part. When flash occurs it means that the plastic pressure in the cavity exceeded the clamp force, forcing open the mold parting line enough to allow plastic to flow into the parting line. Flash can be eliminated by several different molding techniques. This SkillBuilder lesson explores all the possible solutions for eliminating flash on a molded part including, high or low melt and mold temperatures, high packing and holding pressures, unbalanced pressure distribution in the mold, parting line damage or too deep of a vent channel.
12
Lesson 4 - Solving Sink marks on a Molded Part. Sink marks in a molded product are caused by plastic shrinkage. The packing and holding phases of the molding cycle are designed to reduce and control the amount of shrinkage by putting more molecules in the cavity. In thick sections, like where walls and ribs and bosses meet, the plastic shrinks more. This is where you often see sink marks occur. This SkillBuilder lesson challenges the student to solve this problem in a variety of different ways. Both mold temperature and injection pressures are experimented with to demonstrate to the user more than one possible solution to the problem.Lesson 5 - Identifying and Solving Voids in Molded Parts. Voids in a molded product are caused by the plastic shrinkage. Voids and sink marks are often interchangeable. In thick sections, if the wall of the part is frozen very quickly, and the plastic inside the part is still shrinking, this shrinking material can sometimes pull itself apart, and a vacuum void is created. Voids are easiest to spot on clear parts or if a colored part is cut open. Vacuum voids often have little effect on the appearance and functionality of a part. The solutions for voids and sink marks are often a trade off of one defect for the other. This SkillBuilder lesson allows the molder to adjust machine controls to create, then solve each problem. In this way, a deeper understanding of the problem is realized.Lesson 6 - Minimizing Weld line Formation and Appearance. Weld lines are caused when two plastic flow fronts are split, and then rejoin during cavity filling as when plastic flows around a boss, for example. The strength of a weld line can be from 40% to about 95% the strength of the surrounding plastic, depending on the type of plastic and the molding conditions, like melt temperature, mold temperature, holding pressure and fill rates. The purpose of this SkillBuilder lesson is to show molding techniques on how to reduce and even eliminate the visual appearance of weld lines on a molded product.
