Ever look at a molded rubber part and ask yourself “how do they make that”? Those of us that had toys that would surely be ruled as unsafe for children today, just might have had a small rubber molder.
The advantages of being able to create worms, spiders, and cockroaches that looked, real but did not hurt when your older sister threw it at you...was priceless. I had no idea at the time, but it served a my introduction to the rubber industry. I’m sure I used that machine until I ran out of the included silicone compound, or until I burned myself one to many times.
I did not know it at the time, but my process for making worms and spiders was compression molding. My spiders were made using what amounted to a hot plate, with attachable molds. Select your mold, add enough compound to fill the mold with minimal excess (see flashing). Close the lid and turn on the hot plate. After waiting the prescribed amount of time, turn off the heat & let the mold cool. If your impatient like me, this is where you burn your fingers. Once cool, open and gently remove the spider from the mold, being careful not to remove it too quickly and tear the legs off, or leave legs in the mold (which will ruin the next spider).
Today I’m out of the spider making business. But having that childhood experience helped me to understand what was happening the first time I stood in front of a multi-mold compression press producing thousands of parts for the oil industry.
Now at American Seal & Packing, we can offer custom made shapes, from o-rings to golf grips and well head components utilizing Compression Molding, Transfer Molding or Injection Molding. Each method has it’s own advantage.
Compression Molding is the ideal method for medium-sized and large items produced in small to medium batches. It is also the best method for expensive rubber types such as Viton® and Aflas®, FFKM, and applications which require extreme rubber hardness.
Advantages:
Low mold production costs
Short tooling times
Helps in the processing of rubber types which are difficult to work with Excellent for products with high density and therefore long process times
Transfer Molding - combines the advantages of injection molding with the practicalities of compression molding.
Advantages:
Perfect for items with complex design
Provides short lead times
Allows narrower dimensional tolerances than compression molding
High uniformity with little flash
Quick tooling
Suitable for micro-components (like injection molding)
Injection Molding Rubber injection molding is the ideal method for the mass production of small or medium-sized items, complex inserts, items with narrow dimensional tolerances and components which require high uniformity. Liquid Silicone Rubber molding is another injection method we can offer. Similar to rubber injection molding, it offers the advantage of speed for high volume production.
Advantages:
Short molding process
Low unit cost
Narrow cross sectional dimensional tolerance
Minimal flash
Minimal waste
So, if your in need of high volume parts, low volume with low tooling costs, or small parts with high detail, we have the best method available to produce your parts.
