Location

Location depends on whether there was land or a property available when they located and whether or not there is any zoning.  Pretty much an injection molding plant can go anywhere.

Thank you Dave!

By zoning, i assume if industrial usage was/is allowed then an injection molding industry is a go right?

Yes

An injection molding company is a pretty "low impact" industry, they are in mixed use areas all over the place.

Very very helpful!

Many thanks Dave for confirming this. It really helps out to retain the plant at the current spot on the layout!

location: Anywhere in anything!

I worked in a molding company for a few years... I've seen many locations.

The one I was working in was a repurposed plant from DuPont. In WWI it was used for munitions. Heavy brick construction.

Our other facilities were similar to any strip mall construction (like a small scale Home Depot, less the facade). Only 3 of our 7 had a rail facility.

But location was never 'IN" the dense part of town.

Location

I worked a couple years in a extrusion plant, 3rd shift. Located away from the tracks in a modern industrial area. The building was basically a long Morton type metal wall building. Pellets came in by truck or rail delivered to the lumber yard track down the street all in big boxes on pallets. From the lumber yard to our building was in our box truck. I can’t think of the name of the box type they came in but roughly 4’x4’x4’. Extrusions left by trailer only. Location for an extrusion plant could be any where the business and building codes allow.

Pasadena Industrial area 60s

Thank you all for your replies!

With respect to Pasadena in the 60s, i noted that there were quite a few industries in the industrial area south of the main depot, such as lumber, oil-dealer, cement-dealer, Frozen foods, power plant.... (but no plastics molding plant, so i freelance a bit here).

Today it looks very different but even today i noticed that the said area does allow for industrial uses. So based on these and the input from Dave (Husman), i am hoping that i could place the plant there. I reckon it's impact won't be too different to that of a furniture factory (which is the other industry that can exchange places with the molding plant on my layout).

When a couple of friends and I were exploring the LAJ,

We found a siding in City of Commerce across the street from the LAJ's "C" yard that had a couple of pellet hoppers spotted.  As far as I know it was not a plastics plant, but was used like a team track.  When the pellets were needed, a truck came by and loaded pellets out of a hopper.  I don't know if it was something shared by more than one company or if the cars were only unloaded by one company.  I know a truck was used to unload the pellets because it came by, unloaded pellets and left while we were in the area.
