Plastic Injection Molding Service Online

Plastic injection molding service is the process of melting various plastic pellets (thermosetting/thermoplastic polymers) that once are melted to be malleable enough, are injected at pressure into a mould cavity, which fills and solidifies to produce the final product using a vertical or horizontal injection molding machine.

We support three types of Injection Molding Machines as follows:

1. Horizontal Injection Molding Machine
2. Vertical Injection Molding Machine
3. Desktop Injection Molding Machine

We support parts that weigh as low as 1 gram to as high as 900 grams. 

Horizontal Injection Molding is an Industry standard across many countries due to their ease of use and familiarity. These are best suited for most applications where the part size is large and require industry-standard tolerances 

Vertical Injection Molding Machines are an improvement over horizontal machines by improving the tolerances as well as reducing the failure rate. Medical Applications make the most out of it. 
The only setback is the limitation of the size of the part manufacturable with Vertical Machine.

Desktop Injection Molding brings the output quality of the professional Injection Molding Machines on a desktop-grade machine. 
Suited for a lower number of parts as the cost of parts is higher than the other two injection molding services.

• Wall thickness Thickness: 1 mm and 3 mm
• Smooth transitions 3 × wall thickness difference
• Rounded edges - Internal edges: > 0.5 × wall thickness
• Rounded edges -External edges: internal fillet + wall thickness
• Draft angle - for parts taller than 50 mm: increase the draft by 1° for every 25 mm
• Draft angle -For parts with a textured finish: increase the draft by an extra 1°-2°

The minimum order quantity is 100 runs per mold.

Steel P20, Carbon Steel S50C, Aluminum, and more. 

Production inspection reports, full dimensional report, material certifications as well as factory inspection certification available. 

Standard Finish
Moldmaker's choice of finish. Typically SPI B-3 to D-3 depending on geometry and drafts. Interior, non-cosmetic faces, are typically as-machined.

SPI Finishes
Range of finishes from Grade 3 diamond / high polish to 320 stone low polish. Finishes include: SPI A-1 , SPI A-2, SPI A-3, SPI B-1, SPI B-2, SPI B-3, SPI C-1, SPI C-2, SPI C-3, SPI D-1, SPI D-2, and SPI D-3

MoldTech Finishes (Mold Texturing)
Range of finishes including matte, swirls, lines, and patterns. Our most common texture finishes include: MoldTech MT11010, MoldTech MT11020, and MoldTech MT11030. Other textured finishes can be added by request.

As Molded
No secondary polishing or grinding. Part will show tooling marks.

Threaded Inserts
We can install most commonly used standard inserts in UNF and metric sizes.

Pad Printing
Transfer a 2D image onto a 3D part. All images are subject to review.

Laser Engraving
Engrave part numbers, logos, and more onto your parts.

Assembly
Makenica has the ability to assemble & label molded parts. Discuss your needs with your salesperson available at support@makenica.com?

Typical tolerances are +/- 0.005" when machining the mold and an additional +/- 0.002"/in when calculating for shrink rate.

Almost any category that sells physical products use injection molding. Some of those industries are:

1. Automotive Mould
2. Aircraft Parts
3. Home Appliance Mould
4. Household Plastic Mould
5. Medical Molding
6. Connector Mould
7. Crate Mould
8. Package Mould
9. Optical Reflectors
10. Cooking Utensils
11. Medical Devices
12. Handles and Knobs

While there are many benefits to Injection Molding, we have summed up a few that are highly critical:

1. Detailed Features and Complex Geometry
2. Fast production and highly efficient
3. High-output production
4. Large material choice
5. Product consistency

A mold core is a device used in casting and moulding processes to produce internal cavities and re-entrant angles. The cycle begins when the mould closes, followed by the injection of the polymer into the mould cavity.

If we skip the cost of injection CNC mold then the same part would cost as follows:

1. 3D Printing -> INR 4500 for 1 part
2. CNC machining -> INR 7000 for 1 part
3. Urethane Casting -> INR 4000 for 1 part
4. Injection Molding -> INR 60 for 1 part

The cost of injection mold starts from $1000 or INR 60,000

Here are some ways to reduce the overall cost of your injection molding manufacturing:

1. Eliminate undercuts (highly effective)
2. Get rid of unnecessary features
3. Use a core cavity approach
4. Reduce cosmetic finishes and appearances
5. Design self-mating parts (avoid snap-fits)
6. Modify and reuse existing moulds
7. Get Professional DFM analysis done
8. Use a multi-cavity or family mould
9. Consider reducing the overall part size

In soft-tooling, the injection mold is made out of Aluminium which is easier to CNC which results in reduced mold cost. (Mold Life: ~50 Thousand)

Whereas, hard-tooling is made using steel which lasts longer than Aluminium mold but has a higher upfront cost. (Mold Life: >500 Thousand)
