ADDITIONAL SUPPLIES

Spare Nozzle Ring

A nozzle ring is already included with the purchase of the PIM-MODEL-20A.

However, if you need spare nozzle rings, you can purchase extra ones here.

Quick Release Toggle Clamp

For faster production, you can use this quick-release toggle clamp to hold the mold instead of a manual vise.

The adjustable mold stop and the toggle clamp will speed up the entire molding process. You can see this accessory in action by going to the VIDEOS section of the Model 150A page.

Aluminum Frame for Epoxy Mold

This is an aluminum frame with an inside cavity where you can pour in epoxy to make your own mold. The frame has two steel pins and holes to keep the two halves exactly aligned with each other. Once the epoxy mold is cured in the frame, it can be removed in order to use the frame to make additional epoxy molds.

Outside Dimensions: 4.0"W x 3.0"H x 1.5"D
Inside Cavity Dimensions: 3.0"W x 2.0"H x 1.0"D

Puzzle Piece Mold

This mold allows you to create fun puzzle piece parts.   Four of the puzzle pieces can be interlocked together.   The molded pieces have a round cavity on the back where you can glue a small magnet to turn them into refrigerator magnets.

Great for trying different colors and materials!

500 cc BOTTLES

PLASTIC PELLETS

We are offering limited quantites of a variety of thermoplastic pellets. You may want to try various plastics to determine the best type of material for your needs. If you plan to  

All pellets offered below have been tested with the Model 150A injector.

The pellets are sold by volume and are packaged in a 500 cc (16 oz) bottle.

NOTE: We cannot provide MSDS sheets for these materials and some settling of contents may occur during shipping.

The molding temperatures listed for each material are only recommended starting temperatures. Details about optimizing molding temperatures are included in the operations manual.

POLYPROPYLENE (PP)

FEATURES

Polypropylene is a common thermoplastic resin typically used for injection molding applications. PP offers a good balance of properties and cost, uncommon to most other thermoplastics. PP provides outstanding physical, chemical, mechanical, thermal, and electrical properties not found in any other thermoplastic.

• High Strength
• High chemical resistance
• Abrasion resistance
• Machinable
• Excellent electrical properties

Brown Polypropylene Pellets

Suggested molding temperature is: 400 deg F.

This brown polypropylene (PP) has a melt-flow value of 30 and is very easy to inject.   The mold will need slight pre-heating for best results.   This is a good all-around general purpose material.

Black Polypropylene Pellets

Suggested molding temperature is: 420 deg F.

This black polypropylene (PP) has a melt-flow value of 30 and is very easy to inject.   The mold will need slight pre-heating for best results.   This is a good all-around general purpose material.

Natural Polypropylene Pellets

Suggested molding temperature is: 420 deg F.

These are natural (uncolored) polypropylene (PP) pellets.   The molded items will be translucent (not transparent).   This material is fairly easy to inject and the mold will need some pre-heating for best results.   This is a good all-around general purpose material.

POLYETHYLENE (PE)

FEATURES

POLYETHYLENE is widely used for manufacturing various containers, dispensing bottles, wash bottles, tubing, plastic bags for computer components, and various molded laboratory equipment. It is translucent to opaque, virtually unbreakable, and very flexible.

• Corrosion-resistant
• Solvent-resistant
• High flexibility
• Lightweight
• Machinable

Natural Color HDPE Pellets

Suggested molding temperature is: 420 deg F.

POLYETHYLENE (PE) is widely used for manufacturing various containers, dispensing bottles, wash bottles, tubing, plastic bags for computer components, and various molded laboratory equipment.
HDPE has excellent tensile strength, energy consumption, abrasion resistance, and resistance to stress cracks, and good chemical resistance and electrical properties.
Injection-molded HDPE is resistant to warpage and distortion.

Natural Color LDPE Pellets

Suggested molding temperature is: 340 deg F.

Low Density Polyethylene (LDPE) is often used to purge other materials from the machine, but can also be used to mold finished parts.   The pressure needed to inject this LDPE into the mold cavity is a bit higher than some of the other materials listed.

Light Blue LDPE Pellets

Suggested molding temperature is: 430 deg F.

This is Low Density Polyethylene (LDPE) with a light blue color.   After injection the parts appear to have a nice shiny surface.   This plastic is easy to inject and produces nice looking parts.

Yellow LDPE Pellets

Suggested molding temperature is: 430 deg F.

This is Low Density Polyethylene (LDPE) with a Beight Yellow color.   After injection the parts appear to have a nice shiny surface.   This plastic is easy to inject and produces nice looking parts.

Acrylonitrile Butadiene Styrene (ABS)

FEATURES

ABS is often used to make light, rigid, molded products such as piping, musical instruments (plastic clarinets), golf club heads (used for its good shock absorbance), automotive body parts, wheel covers, enclosures, protective head gear, and toys including LEGO bricks.

• Very high impact strength
• Tough, hard and rigid
• Electroplatable
• Dimensional stability
• Poor solvent resistance

Black ABS Pellets

Suggested molding temperature is: 440 deg F.

This material is Acrylonitrile Butadiene Styrene (ABS).   ABS is a very common thermoplastic. It is tough and rigid and has good chemical resistance and dimensional stability.   This ABS has a fairly high Melt Flow Index which helps it flow better in our machines.   The color is black.  

Natural Color ABS Pellets

Suggested molding temperature is: 440 deg F.

This material is ABS.   ABS is a very common thermoplastic. It has good chemical resistance and dimensional stability.   This ABS has a high Melt Flow Index which helps it flow better in our machines.   The color is natural.  

Red Color ABS Pellets

Suggested molding temperature is: 440 deg F.

This material is ABS.   ABS is a very common thermoplastic. It has good chemical resistance and dimensional stability.   This ABS has a fairly high Melt Flow Index which helps it flow better in our machines.   The color is almond which appears as a pale tan.  

ELASTOMERS (TPE)(TPO)(TPV)

FEATURES

TPO/TPE/TPVs can be over-molded onto substrates made from Polypropylene (PP), Nylon (PA), Polycarbonate (PC), Acrylonitrile-butadiene-styrene (ABS), PC/ABS alloys, and metals. Or they can be used to mold "rubber-like" parts.

• Recyclable
• Flexible
• Lightweight

Black TPV Material

Suggested molding temperature is: 385 deg F.

This material is a thermoplastic elastomer vulcanate (TPV).   TPV's show advantages of both rubbery materials and plastic materials. Molded parts are flexible and have a soft rubbery feel.   This material is very easy to inject and the mold requires little or no pre-heating. Shore Hardness is 60A.   Perfect material for beginners.

Brown TPE Material

Suggested molding temperature is: 400 deg F.

This material is a thermoplastic elastomer (TPE).   TPE's show advantages of both rubber materials and plastic materials. Molded parts are flexible and have a soft rubbery feel.   This material is very easy to inject and the mold requires little or no pre-heating. It is more flexible than our TPE Black material.   Perfect material for beginners.

Natural TPV Pellets

Suggested molding temperature is: 385 deg F.

This thermoplastic Vulcanizate (TPV) is a High Flow Grade elastomer that is BPA-free and RoHS compliant. It can be used for soft touch grips, gaskets, as well as replacing silicon in some applications. Excellent at bonding to Polypropylene.

TPV's show advantages of both rubbery materials and plastic materials. Molded parts are flexible and have a rubbery feel.
