APSX-PIM Plastic Injection Molding Machine

APSX-PIM can process any plastic including but not limited to Polypropylene (PP), Polyethylene (PE), Thermoplastic Polyolefin (TPO), Nylon, Polycarbonate (PC), Acetal (Delrin), ABS, PC/ABS with MFR (ASTM D1238) > 10 g/10min). IN CASE YOU ARE NOT SURE ABOUT YOUR PLASTIC RESIN SELECTION, ASK US. 

Since 2017, we have improved this machine that makes plastic injection molding affordable and easy. Today, the APSX-PIM is an alternative to the traditionally expensive, overpowered and large injection molding machines used for R&D, prototyping, product design, education, research and other plastic part production environments.

This plastic injection machine creates quality parts that are consistent, easily repeatable and affordably produced. You can create low-cost components rapidly without complex setup or large up-front costs. 

All components of this machine are made in Cincinnati, OH USA.


- Compact design
- Strong body structure with stainless steel, hard anodized aluminum, bronze parts
- All electric and no water-coolant system
- Full automatic with precision sensors
- Injection speed control for fill rate
- Electronic temperature control system
- User touch screen for operational control
- Typically 60 secs per injection cycle (clamp opens and ejects parts every 60 secs)

Small Size without the Compromise - a real injection machine without the typical compromises of desktop injection presses. The APSX-PIM can be moved into nearly any workbench and requires only basic 120VAC wall outlet to operate, but has the ability to make parts much more than a rough draft prototype plastic part. Standard mold size is 6" by 4.8" as it is stated for the Blank Mold available here

Affordable Precision and Repeatability – smaller doesn't mean less capable. The APSX-PIM uses the latest available technology for precision and repeatability. 

Low Cost of Ownership – most small injection machines are more style than substance, with designs that are expensive and difficult to maintain without an experienced technician. APSX-PIM is an easy-to-maintain and affordable to run desktop injection machine in both R&D labs and small manufacturing shops.

With the APSX-PIM, we set out from the beginning to create a new type of desktop injection machine – a design that combined all the attractive features of a desktop injection machine with the performance of a large size full automatic injection machine.


What are the suggested plastic material specs for the best injection performance out of APSX-PIM?
We suggest using a standard size (0.125" diameter) virgin plastic pellets. As a general rule, the machine will perform "better" with high melt flow rate (MFR) materials. It all depends on the mold design. It has to be designed for 5000 PSI injection pressure and 5 tons clamp force. Typically we have been using materials with 10 MFR and higher. Any plastic including but not limited to Polycarbonate (PC), Acetal (Delrin), ABS, PC/ABS, Nylon (PA6), Polypropylene (PP), Polystyrene (PS), Polyethylene (PE), Thermoplastic Polyolefin (TPO) can be used with MFR (ASTM D1238) > 10 g/10min or MFR (ISO 1183) > 30 g/10min and viscosity value less than 1500 poise.


What kind of mold do we have to design for APSX-PIM?
APSX-PIM provides 5000 PSI injection pressure and 5 tons clamp force. Given that, a mold maker should design the mold according to these machine specs. All of the features such as draft angle, wall thickness, one or multi-cavity mold decisions have to be made considering the injection molding machine being used. All parts are unique and so all molds are too.

There is a scientific relationship between the part size and the pressures applied to the mold. The initial injection pressure does not create high pressure inside the mold but the flow rate can. Once the machine drops to holding pressure about 90% of the part volume is injected into the mold, the mold gets pressurized. On the other end of the machine, clamp force holds the mold closed so that there is no flashing on the part.

The rule of thumb is that Holding Pressure X Footprint Area of the Part on the mold face < Clamp Force. The footprint area is defined as the largest projected area of the part on the vertical face of the mold perpendicular to plastic flow.

What is the approximate max size plastic part that APSX-PIM can make?
The visual below should help you understand the ballpark figures for the max size parts in question. The critical piece here is the plastic footprint of the part on the mold face. .

What is the maximum shot size that APSX-PIM can perform?
Max shot size is 1.83 cu-in or 30 cu-cm. About 95% of the max shot size shoud be achievable although it may vary due to mold design. Typically it corresponds to a max 30-35 gr in part weight since each plastic density value are different from each other.

What are the maintenance requirements?
There is no frequent maintenance activities involved. However, be sure that the hopper has material in it and hopper pipe is cleared from any obstructions from the previous injection sessions. The shafts may need an extra lubrication after being used for a long time (approximately 500 hours) to allow the shaft bushings to slide with less friction. We recommend using synthetic 10W-30 oil, applying an even coating on the shafts.
