What is Injection Molding?

Injection molding is a manufacturing process used to produce precise, cost-effective parts, typically from plastics, in high volumes.

The process involves injecting molten material into a custom-designed mold, which defines the part’s shape. Once the material cools and solidifies, the mold opens and the part is ejected.

This process is ideal for creating complex parts with tight tolerances, making it popular in industries like automotive, medical devices, and consumer goods.

Jiga's Buyer Protection

Since partnering with Jiga, we’ve seen some considerable cuts in our lead time and pricing. We used to have upwards of eight weeks before I would see parts that I’ve ordered. Now I’m seeing them two or three weeks later. Jiga’s communication system on their website is paramount to getting these orders through. I can talk to each individual vendor based on that order. Response times are fabulous. I get responses back within the day, even if it’s overseas.

In an industry where competitors often act as mere middlemen, Jiga truly stands out by empowering buyers. Their platform enhances communication with suppliers, streamlining the entire process. The easy payment system simplifies interactions with overseas vendors, eliminating the hassle of dealing with international transactions. I’ve found such value in Jiga that I’ve recommended it to all my colleagues in manufacturing.

Jiga has been an unbeatable combination of speed, quality, and price! I really like the streamlined communication platform directly with vendors, and I appreciate the prompt attention of our account manager! I have sourced a variety of custom metal parts so far and it’s been a flawless experience.

I am continually impressed not just by the parts we have received but the incredible level of support. Our team has received 100s of parts, all at an incredible price. Because you have a direct line of communication with the teams making the parts, there is an added level of ownership that you don’t see with other platforms. We are actively switching to have more parts made on Jiga to further drive down costs and have reliable delivery dates.

There are many companies are in the quick turn space, but Jiga stands out. Why? It’s so easy to quote with multiple vendors, view and track everything, set up a team and share information and have coverage when you’re on vacation. No other company in this space has nailed quoting, vendor communication and team capabilities like Jiga has. Add their great customer service and it’s a really great experience.

Injection Molding FAQs

What injection molding services are provided?

Plastic Injection Molding, Overmolding (adding rubber/silicone or other over an existing part), and Insert Molding (integrating pre-formed inserts into the part). Learn more here

Jiga supports a wide range of thermoplastics, including ABS, POM, ASA, HDPE, HIPS, LDPE, Nylon, PBT, PC/ABS, PEEK, PET, and polycarbonate, as well as specialty options like glass-filled materials.

A variety of finishes are offered, following SPI and PM standards (such as SPI-C1, SPI-B1, PM-T0, and more). Additional finishing options may also be available depending on your tooling and material choice.

Injection molding typically has a higher upfront cost due to mold tooling, but it becomes cost-efficient at scale. Jiga utilizes rapid tooling to reduce lead times, enabling faster iteration.

All molded parts come with strict quality control, including ISO-certified processes, Certificates of Conformance (CoC), First Article Inspection (FAI), CMM reports, material certificates, and RoHS compliance.
