CAD-CAM Progrom

Tutorial CD-ROM Introduces Merits of CAD/CAM Program

SINCERE TECH mold Corp. is offering a free tutorial CD-ROM for its ST CAD/CAM software. The CD, first in a new “Getting Started” video series, is designed to take a user step by step through the construction of a single product. This first CD covers fundamentals such as program navigation, initial hybrid 3D models, automated drawing, layout, and dimensioning as well as “power user” hints.


SINCERE TECH MOLD Corp. is making its CAD/CAM software easier to learn through a series of “Quick Start” tutorials available on-line and on CD-ROM. The tutorials feature a presentation by a ST expert who guides the new user through the design of a single product. Each video segment includes a step-by-step “live action” sequence of menu picks and on-screen results, followed by a single-screen summary of the steps, as shown here.

long the way, users learn about the time-saving benefits of seamless hybrid mixing of solids and surfaces to build components quickly. A variety of surfacing operations create an ergonomic, aesthetically pleasing TV remote control complete with Class A surfaces. Other video segments guide a user through shelling and mold tools, including the automatic calculation of parting lines and separation into plastic mold cavities, as well as easy updating of components through the ST history and rules manager.

Plastic Injection Molding Parts

Plastic Injection Molding Parts

For 39 years Quashnick Tool Corporation has developed custom plastic mold for the who’s who of technology companies in the greater San Francisco Bay Area.
Knowing what’s at stake when it comes to developing and maintaining quality plastic injection molds and the plastic injection molding parts produced is the secret to their continued success. They realize that when companies begin new designs of molded materials, significant corporate R&D, engineering, manufacturing, administrative and support resources are at stake. Any redundant or rework efforts will add cost, delay time –to- market, and may upset medical device trials and qualification.
With this reality in mind they work with you to look as far ahead as possible in foreseeing and side-lining potential pitfalls in a successful molding program. Quality Pros think of it as it “FEMA” in action. They do this specifically by drawing from their 39 years of experience, merging extensive design and materials experience, with state of the art corporate management and sophisticated engineering and project management skills.
Whether you are looking to work with extremely tight time lines, wish to minimize development risks, want to keep manufacturing local in the greater Bay Area, or you are looking to save costs by building tools at a qualified QTC offshore partner, it pays to have a well versed and professional organization shepherd you through the process.
They’ve delivered success for several hundred companies in the greater Bay Area since 1971. They will deliver success for you.

What is your approach to resolving medical tooling and molding problems?

Answer:

It must be discerned whether the problem is with the materials or the molding before heading towards a resolution. For example, if there is a problem with a plastic part that is due to flash, then it is considered a tooling issue. However, if it is a material that is degraded (i.e. cracking or breaking) in the process of obtaining the parts, then it is a plastic materials problem.

In addition, providing examples of the product or specific examples of where the failure occurs is crucial to analyzing the problem. If it is a tooling problem, the program itself must be reviewed. It should be determined whether the material being used for the tool production is feasible for the particular task. The molding procedures should be assessed as well to see if the process is being done correctly.

Initially, the plastic used in the plastic mold should be properly dried and prepped prior to molding. The molding manager needs the qualifications necessary to run a material through to completion and handle it accordingly. The tooling must be designed for and capable of running the material specified. This includes the appropriate temperature controls (cooling and heating) as well as other specifics related to the material. Clearly defining the problem leads to a more effective resolution.

We realize that our success is wholly dependent upon the long term success of our customers and their continued business. We support our customers by maintaining  top quality engineering, customer service, tooling, molding and analytical capabilities- all under one roof.  Delivering results for over 35 years from our headquarters in Lodi California, Quashnick Tool makes this commitment to you:  we promise to add value to your program at every stage of the process!

Plastic Injection Molding

Plastic injection molding

Plastic injection molding is the process of injecting melted plastic resin, then forcing it under pressure into a plastic mold, where it cools and hardens.  The plastic mold is then opened, and the part is removed or “ejected”, usually automatically by “ejector pins”, long thin metal rods inside the mould that push through the cavity forcing the plastic part out of the mold cavity automatically as the molding machine opens the mold.

The plastic mold must have a very heavy wall thickness to keep the mold cavity from bulging since the plastic resin, is injected with as much as 20,000 pounds per square inch of pressure. And for the same reason molding machines must be able to clamp the mold shut with tremendous force.

On the top of the molding machine there is usually a hopper which is filled with the plastic resin to be molded, usually in the form of small pellets about 1/3 the size of a grain of rice.  The hopper feeds the pellets into the “barrel” of the machine.

The barrel has a long screw or auger inside, that rotates, forcing the pellets toward the front of the barrel.  The process of auguring the pellets produces a lot of heat, that melts the pellets. Additional heat is supplied to the barrel through the use of heating bands, electric resistance heating elements that wrap around the barrel.

At the end of the barrel there is a nozzle from which the melted plastic resin is ejected into the mold. The nozzle also has electric resistance heating bands wrapped around it.  The temperature of the nozzle is very important, and the temperature is monitored and controlled at the operator control panel.

If the nozzle temperature is not hot enough the plastic can “freeze off”, forming a solid plug that has to be removed before plastic can be injected into the mold.  If the nozzle is too hot, it can burn the resin destroying the plastic before it makes it into the mold.

Most injection molding machines can be run in either manual mode, or automatic mode.  In the manual mode, an operator slides open a door providing access to the mold itself. The operator reaches in and pulls the part out of the mold, then closes the door, and the mold closes, is filled with plastic, cools of for a few moments, and then opens up again. At that point the operator opens the door again, and the whole process repeats.

In automatic operation there is no operator.  The machine just hums along by itself, automatically ejecting the part or parts when the mold opens, and then re closing the mold, injecting the plastic etc.

Plastic injection molds can become quite complex. They usually require water lines to be built into the mold to cool of the melted plastic resin and harden the part, and they have ejector pins that push into the mold cavity as the mold opens, to eject the part out of the cavity.  Often the molded part requires moving metal pieces called “slides” that must pull metal cores out of areas of the part where there is no plastic such as the inside of pipe fittings etc.

There are many different brands and types of plastic injection molding machines that vary in the way they clamp the mold shut and other differences as well. What I’ve talked about is very very basic.

Plastic mold making failure mostly factors of heat treatment of this important aspect of. Because of the above heat treatment of general failure caused by improper accounting for about 50% of total failure mould. In order to give full play to the potential properties of mould steel, mould machining should be conducted after the quenching, tempering heat treatment in heat treatment, heating temperature, holding time, the length of the cooling speed of process parameter selection is not appropriate will be die failure factors. A machined good plastic mould,if lost due to improper heat treatment and its use value, is in the economy and the loss of time is very big, must adopt various measures to prevent mouth
