  M.R. Mold & Engineering Corp. of Brea,         Calif., has upgraded its injection        molding capability to enhance testing and sampling of customer molds prior to shipment.
The firm took delivery Sept. 4 of a 110-ton Arburg 470A horizontal press that is equipped for thermoplastic and silicone processing and is suitable for short-run production volumes. The hydraulic unit replaces an existing 110-ton electric.
The new Arburg has a 30mm liquid-silicone-rubber barrel and screw and a 35mm plastic barrel and screw, extra heating zones, valve gate controls for cold runner systems, vacuum and a robotic interface. Arburg will train the press operators, and M.R. Mold plans to send two technicians for training in scientific molding processes.
Four other hydraulic presses include a 70-ton Arburg Allrounder 370S, a 100-ton tiebarless Engel and two 55-ton Engels.
M.R. Mold is shopping for a laser engraver to meet customer needs for cavity identification and logo imprints, functions that are now outsourced. The device would engrave mold components, a task M.R. Mold does now on computer-numerical-control milling machines.
In-house use of an engraver will free up machine time.
M.R. Mold partners with the Santa Ana, Calif.-based group Science@OC to advance the federal STEM education strategic plan encouraging students in science, technology, engineering and mathematics disciplines.
“We understand the importance of American manufacturing and the lack of education in our society,” said Rick Finnie, M.R. Mold president. “Manufacturing is no longer a ‘dirty’ business. It is our hope to provide shop tours for students to show them from ‘art to part’ how the process works, tying in why math and science are important.”
Finnie aims to promote scientific literacy among Orange County students, make presentations, attend job fairs and bring industry colleagues into the effort.
The firm has developed another proprietary pneumatic stuffer box for higher-volume sampling, short runs or micro molding where a small amount of material is needed. Typical use of LSR in production requires a pumping unit to mix components prior to injection into the mold.
The stuffer box injects a small dose of pre-mixed material into the barrel of a molding machine and eliminates the need to repetitively clean a pumping unit. The new high-volume version has a volume of 78 cubic inches or 3.1 pounds of pre-mixed material, while the earlier low-volume model has a volume of 27 cubic inches or 1.1 pounds of material.
M.R. Mold has hired six persons since April and now employs 30 including seven mold makers and five CNC specialists. The firm seeks more CNC and design talent.
M.R. Mold envisions a 20-percent increase in sales for 2014 vs. its actual 2013 results.

Rogan Adds M.R. Mold Cold Deck System to its Vertical LSR Molding Machine

Northbrook, IL, May 2014 - Rogan Corporation, known for its true two-shot, liquid silicone rubber, and insert molding, has purchased and added a new cold deck system to its vertical Sodick Plustech Liquid Silicone Rubber (LSR) molding machine. The cold deck will reduce the volume of LSR material used during molding by eliminating the sprue and runner waste that occurs with traditional silicone injection molding. The result is a reduction in part costs, material savings, reduced cycle times, and increased equipment utilization. In addition, Rogan customers also experience a significant tooling savings benefit. 

“Given the complexity of the LSR parts that we produce,” states Jim Ritzema, Rogan’s Director of Operations, “customers can realize tooling savings of between $25,000 - $50,000, depending on the size of the mold, by not having to purchase a cold deck system for their custom tooling.” 

The Rogan cold deck is a two-drop system. The vertical LSR molding machine has a rotary platen on the core side, so there are two bottom halves and one top half. When molding a part, the operator is able to de-mold parts and/or load inserts into the B half while the molding cycle is taking place. The result is faster molding cycles and maximum operator efficiency.

Rogan currently has similar cold deck technology in place with its horizontal LSR molding machines. Adding this system to its vertical LSR molding machine provides the company with additional capacity to take advantage of better utilization of equipment. 

“This new cold deck system will further reduce material costs for our LSR molding customers,” says Ritzema. “Unlike waste from thermoplastic molding, which can often be re-ground and re-processed, waste from LSR molding is a loss, and can be a major cost factor, since LSR is a premium material. This is especially true when molding small parts, where typically the runner can often be as much as five times the size of the individual part itself.” 

Rogan purchased the cold deck system from M.R. Mold and Engineering. The system is a split plate design that facilitates ease of cleaning and maintenance. This design also allows for quick material and color changes. 

Using the new cold deck system, Rogan can efficiently mold small parts, as well as larger parts up to 12 square inches.

"Material Selection - 8 Questions To Ask"           

Robert P. Frey, 
Lead Technical Development Engineer

If you've ever wondered how to make sure you get the information needed to assist your customer in selecting the right material for a job, these 8 questions...actually more like 8 subjects to discuss... will likely bring up a lot more questions, but will also get the discussion started and will likely make your customer thing more about his application, and what it really needs.  Included are concerns regarding the chemical, thermal, mechanical and regulatory  environment, as well as a few other topics.
Bob has 40 years of experience in the plastics industry, starting with production jobs at Dow Chemical, then moving to GE Plastics for 7 years of tech support work in the NORYL®, XENOY® and VALOX® resin businesses.  Bob left GE Plastics and spent 7 years self-employed as a consultant, focusing mostly on computerized flow analyses.  During those years, he worked with a broad variety of thermoplastics, both engineering and commodity.  In 1993, Bob re-joined the GE family as the Technical Service Engineer for Polymerland, and stayed with GEPlastics until shortly after the buyout by Sabic. Finding that working for a single resin supplier was "too constricting", Bob moved to PolyOne Distribution in 2008.  This position at PolyOne Distribution includes responsibilities for processing, design, material selection, failure analyses, and education (both internal and external).  Bob has a BSME degree from Case Western Reserve University, in Cleveland, Ohio.  In his current position, Bob has responsibility to support customers in the 14 western United States as well as western Canada and the northern portions of Mexico.

Seminar 2: 2:15-3:00 PM

Shear happens!            
Steven Silvey 
Silveys' Plastic Consulting

Within the injection molding process there are many areas of shear which have an effect both on the plastics in the form of heat impute, to that which is caused by all the restricted areas in the machine, nozzle, and mold feed system.  Understanding the areas and the possible effects can lead to an understanding of what is controllable and easily interchanged from machine to machine as the tool moves yielding another universal setup point to consider. 

Though short the presentation shall cover:
Screw RPM vs surface speed
Temperature raise in nozzles
Shear and flowability
Gate design and effect of injection speeds

Steven L Silvey has many years in the plastic industry with experience in most of the major processing methods. He spent the first 16 years of his career in the custom molding, blow molding, compression and ophthalmic molding/casting businesses with duties ranging from maintenance, set-up/molder, R&D engineer, Tech Service Manager, to Engineering Manager at various companies. In addition he also filled in at Laney College, teaching mold design and part design in the evenings.  Steven than worked at  General Polymers/ Ashland for 15 years, as their technical services engineer covering  the Western region of the United States, Mexico, and Western Canada. In 2003 Steven started applying his knowledge as consultant as owner of Silveys' Plastic Consulting. In this capacity he continues to provide solutions and education to those in the plastic part manufacturing area
He is a graduate of California State University Chico. A Senior Member of SPE, Certified Instructor for RJG Systematic I training course, Certified Plastic Technologist and member at large of Epsilon Pi Tau.

Seminar 3: 
3:15-4:00 PM  

Optimizing Pack & Hold times In Hot Runner Molds
Suhas Kulkarni  

For cold runner molds, the pack and hold times are optimized by conducting a gate freeze study (or gate seal study) where the part weight is recorded as a function of the pack and hold times. When the gate freezes the part weight remains constant with increasing pack and hold times. A second or so is added to the lowest value of time where the part weight stays constant and this number is taken as the total time for the setting of the pack and hold times. However, in hot runner systems or in valve gated systems the gate area always has molten plastic and therefore the above method does not produce acceptable results. A method for optimizing this value in hot runner systems or valve gated systems is proposed based on the Cosmetic and Dimensional Process Window. Experimental results will be shown.

Suhas Kulkarni is the President of FIMMTECH, a consulting firm that specializes in services related to injection molding. He earned his Masters in Plastics Engineering from the University of Massachusetts, Lowell and a Bachelors in Polymer Engineering from the University of Poona, India. He has 22 years of experience as a process engineer. His main area of expertise is Scientific Processing for Injection Molding. He conducts regular training seminars in Injection Molding and has developed a custom software called Nautilus, that aids the complete process development routine to production release. He is a contract faculty at UMASS Lowell and has given numerous presentations and written several articles. He is also an author of the book 'Robust Process Development and Scientific Molding' published by Hanser Publications in 2010.

BEWARE of CHINA! Protect your website!

M.R. Mold & Engineering Corp., Brea, CA, recently fell victim to a different type of cyber crime: website piracy. While surfing the internet for images, M.R. Mold Owner Rick Finnie came across an image that he recognized as his own, and hovered over the image with his mouse to track the source. To his surprise, M.R. Mold’s website did not appear but instead, a company from China by the name of Mold Sourcing China. The website was an exact copy of M.R. Mold’s site, from categories and tabs to all verbiage and images. M.R. Mold’s website had been pirated – copied to the T.

Taking immediate action, M.R. Mold contacted AMBA’s partner law firm Ice Miller to see what could be done. According to M.R. Mold Marketing Director Geri Anderson, its website administrator was a great help and immediately identified the host of the pirated website. “Ice Miller sent out a letter to the host company to cease and desist, accompanied by a 40-page document proving the website was pirated,” said Anderson. “It was a long, arduous process putting together the documentation, but it was necessary to prove the theft.”  It also cost the company almost $8,000 to claim what was their own.

The process took about a month and on January 10, 2014, the pirated site was taken down. Unfortunately, on January 13, 2014, just three days later, the site reappeared using a new host, and the process started all over again. “We went after the hosts instead of the Chinese company because the hosts were in the US and provided a route that was much easier and quicker,” said Anderson. “Going after the registrar would have taken too long and cost too much money.”

Today, M.R. Mold continues its struggle, as the stolen site still contains two categories copied off of its website. To help combat future theft, M.R. Mold recommends taking the following precautions:

-          Watermark all images with company name and/or website. These watermarks cannot be removed and help to protect your property.
-          Register your contact information with Google. Google then checks content information and the author to ensure its validity. If Google finds it is not valid, it penalizes the fake author via Google rankings. This doesn't prevent others from using your content, but it is a deterrent.
-          Conduct periodic searches through your web browser to ensure the integrity of your website.
