profiling moulder productivity.

Mold manufacturers provide useful advice for tool room technicians and mold operators.
Across the country, many mold operators spend more time understanding what is needed to make tools, and more tool room operators spend more time understanding how the molds work. Call itcross-
Training, but in many woodworking operations, the boundaries between the mold operator and the tool room staff are slowly disappearing because of the lack of skilled help, or because a company wants to expand the responsibility of the staff to let them
An efficient mold/tool room team of employees who know the whole operation can reduce the set-
Increasing time and productivity, especially as short-term production continues to be the norm.
\"When I first started working as a mold operator, I knew very little about making knives in the tool room,\" said Bob mullaida, a star styling Foreman at Bedford.
Custom mold manufacturer.
But that changed.
In today\'s mold operation, the operator cannot only operate the mold, and the tool room technician cannot only manufacture the tool.
It is important for both teams to understand the work knowledge of each other\'s departments so that they can quickly design and produce knives to help reduce the setuptimes.
\"Therefore, when purchasing new molding equipment, the skills and comfort of the machine operator and the staff of the tool room must be taken into account.
Both parties must be able to master the correct operation of the equipment, necessary adjustments and requirements.
Wood and Wood Products asked several machinery manufacturers what technologies could be used to help both parties achieve these goals.
We found that matching the processing and feeding speed requirements increased
Improving precision and cutting head technology are several areas that help the company achieve its production goals.
Setting production targets in addition to the accuracy of the machine and the ability to provide rapid conversion, the feed rate is an important consideration when purchasing the molding equipment.
The three popular options are the connected mold, single knife mold and the planing machine mold.
While the general concept of wood for these different types of molding machines is similar, their productivity and the ability to perform specific molding functions vary greatly.
For companies looking for molds with high feeding speeds, joint molds are often considered a popular option.
However, they account for only a small part of the moldy market.
\"Companies like Georgia use these molds
Pacific andfloating company needs a fully formed copy machine, producceup 35,000 feet
\"Hour shift,\" said TimSermonet, mold sales engineer at SCMI. These high-
According to Sermonet, the speed machine does have some drawbacks.
In addition to being more expensive, the joint machine will need more time to make setup changes and the operator will be required to provide a higher level of skill.
\"Machines connected by water and electricity
Need to use high matching lock
\"The pressure grease gun,\" Sermonet said . \".
\"The result is that all the knives are on the same cutting ring so you can run at a higher feed rate.
Single though
The cost of the die machine is not as high as jointedmoulers, and they can still provide attractive profiles, feed speeds, quick setup and easy operation.
\"Depending on the type of wood being formed, the single Knife machine can run well at 35 feet per minute,\" Sermonet said . \". \"In a seven-
The hour shift can be translated into 14,000 feet.
\"The difference between the planters is that they do not provide any profiling capabilities.
The only operation of the machine is the four-sided surface (S4S).
\"These machines provide two kinds of feed speeds,\" Sermonet said . \".
\"The slow feed speed of about 19 feet per minute provides more knife marks per inch for finer finishes, while the higher setting of about 38 feet per minute provides higher productivity. \"Electronic-
In addition to having a well, it also helped setupsIn
Trained staff in the mold/tool room department, the operation cannot be produced and profitable if itsmoulder is not running.
However, electronic digital readings are used without computers and CNC (
Computer numerical control)
The control helps to install the mold more easily, efficiently and cost-effectively, and to improve accuracy.
The electronic digital reading provides convenience and efficiency in the machine settings without the additional cost of CNC control.
This makes the machine more affordable and easier to learn to operate.
\"Five years ago, a skilled set of workers took 25 to 35 minutes to replace the cutter head and make the right adjustments to the machine,\" Sermonet said . \".
\"Today, with the help of electronic and mechanical digital readings, our machine conversion time is not only three or four minutes, but it is no longer necessary to run the sample parts in the machine to check the accuracy.
\"The CNC worth a look removes speculation from the mold settings, which is a major goal for companies that can afford the extra cost of CNC
With the addition of CNC, many mold manufacturers have greatly reduced the time required between profile changes, can meet strict tolerance requirements and provide production information.
\"Computers eliminate human errors and do what they should do,\" said Bob Meadows, consultant for woodworking machinery . \". \"The CNC-
The controlled die-cutting machine can also eliminate the operation of the waste through the machine to obtain the correct measurement results.
You just punch holes in the next profile and the Machine will automatically adjust to the next setting, \"he added.
In addition to adjusting to the next required position, the mold with cnc control is able to provide more information to the operator.
Therefore, machines can produce important information as a method of production management.
Gary Fredriksson said: \"Some moldy computers can track the work that is running, how many board feet are being produced, and even who is operating the machine, and when they are resting, sales and marketing director of Deere machinery.
These computers can even help find production.

Jon Morris, marketing manager at Michael Weinig Inc. , said: \"The central lock tool eliminates the many screws needed to lock the cutter on the cutter head . \"
\"The center lock tool requires only one screw to clip the knife into the knife head.
A lot of time is saved due to the elimination of many additional screws.

According to Fredrickson, this should be taken into account when using a single gallows, which is an additional cost and saves a lot of time.
He said that the cost of the center lock knife head may be 30% more than the multiple gib screw knife heads, but he added that saving time can cover additional costs depending on the frequency of the knife head replacement
One goal to meet the future mold design is to increase the symbiotic relationship between the mold operator and the tool room technician for quick replacement.
The new cutting technology, computer systems and safety mechanisms are several areas of future mold technology trends mentioned by mechanical manufacturers.
\"Programming the mold is easy so it can be set up quickly for the next job, but if you don\'t have a knife you won\'t be able to run the job,\" Fredrickson said . \".
\"It is a very time-consuming process to accurately place the knife on the knife head.
In the future, we may see tools and grinding operations that do not require a template, just using a computer of the right size to cut the tool.
\"Computer integration is expanding due to the low efficiency, precision and production costs of the molding equipment.
The key is for manufacturers to design computer systems so that machine operators and tool room engineers are not intimidated by them.
\"Communication between machines and computers will definitely increase,\" said Meadows . \". \"User-
Friendly Computers are necessary because it is increasingly difficult to find skilled workers to operate the machine.
