Plastic Molding Icon

Plastic Molding

A cost-effective solution for a wide range of products. GPI capabilities include injection molding, compression molding, blow molding, rotational molding, and extrusion molding.

Common plastic molding materials include acrylic, PVC, polypropylene, polystyrene, and ABS.

Printing Icon


A secondary process that adds aesthetic value or provides additional information for a product. Applications include text, graphics, designs, patterns, instructions, and labels to make your product and retail packaging stand out.

GPI capabilities include litho, silkscreen, heat transfer, hot stamping, tampo/pad, and dye sublimation printing.

Manufacturing with Textiles Icon

Manufacturing with Textiles

Common materials in textile manufacturing include cotton, nylon, and mesh.

We’re experienced with silkscreening and digital printing on fabrics, sourcing and custom manufacturing plush, and storage bags in a variety of materials and styles.

Vacuum Forming Icon

Vacuum Forming

Used primarily for the production of lightweight plastic components. During vacuum forming, the material is placed over a mold and heated until it becomes flexible. Vacuum pressure is then applied to shape the material against the mold.

Vacuum forming is a great solution for securing and displaying products in retail packaging.

Die Casting Icon

Die Casting

A manufacturing solution to create molded components out of metal. The metal is heated until it becomes molten and then poured into a steel mold.

Die casting is commonly used for aluminum, copper, bronze, brass, and other alloys.

Metal Stamping Icon

Metal Stamping

Think of metal tins used for retail packaging. Tooling bends and presses metal into a three-dimensional form. This method is cost-effective for larger production volumes.

We’re very experienced with creating custom shapes and printing directly onto metal.

GPI’s Manufacturing Process

Customers partner with GPI to avoid the headaches of overseas manufacturing. It can be difficult to know which factories to work with, how to ensure they manufacture your product exactly as needed, and what it takes to oversee quality and stay on schedule.

GPI is highly experienced with working with factories overseas—we visit the factories we work with and know their people and processes inside out!

Here’s how our process works:

  1. Submit your product specifications to us. This could be the proverbial “cocktail napkin sketch” or highly detailed CAD files and 3D models.
  2. We’ll finalize your product design with you and provide a custom manufacturing quote.
  3. We’ll select a manufacturer from our carefully vetted network and communicate all of your requirements.
  4. You’ll receive preproduction samples for your approval. We don’t authorize our factory partner to commence production until you’re satisfied.
  5. We’ll manufacture your product as soon as you’re ready to proceed.
  6. You’ll receive postproduction samples to approve before your products are delivered to the overseas shipping port.
  7. We can also coordinate product safety testing and arrange to ship your products anywhere in the world.

You’ll have a dedicated GPI team of representatives who will proactively manage your project, communicate updates, and answer questions every step of the way.

Why Choose GPI for Custom Manufacturing Services?

Personal Relationships with Overseas Manufacturers

We maintain close relationships with an intentionally small network of factories in China and Vietnam. We do not put projects “out to bid” to dozens of unknown factories.

Instead, we partner with manufacturers that we have known personally for decades. We visit their factories, meet with their production planners and quality control teams, and work collaboratively to ensure attention to detail and adherence to control is their top priority.

Project Management from Start to Finish

The product manufacturing process has hundreds of moving parts that must all work together to deliver a quality product on budget and on time.

Our comprehensive project management can help you avoid the common pitfalls of custom manufacturing: sourcing issues, supply chain delays, defective products, shipping challenges, and more.

Expertise in a Wide Range of Manufacturing Solutions

Our team can guide you on manufacturing methods, product design, materials selection, and packaging efficiencies.

From high-volume injection molding to custom products with complex component sourcing and assembly requirements, we are committed to finding the right solution for your project.

FAQs on Custom Manufacturing Services

How long does it typically take to manufacture a product?

Lead times typically run 45-60 days once all approvals are in place and production is ready to begin. You’ll also need to account for shipping and delivery in your timeline. We can provide you with a more specific timeline for your project once we understand your requirements.

Will I be able to see samples before production?

Yes, you will receive product samples before manufacturing begins on your order. These samples will show you exactly what the finished product will look like.

Once the production is completed, we will send you another set of samples to compare to the preproduction samples. If there are any deviations, we make the necessary corrections before the goods are delivered to the port.

How does the pricing work for custom manufacturing services?

Our manufacturing services are priced at per unit pricing and include all ancillary expenses: expert project management by the GPI team, complete custom manufacturing, full assembly, packaging, and preparation for delivery to an overseas port.

We’ll share pricing options for ExWorks (picked up at the factory location) or FOB port (delivered to the overseas port in China or Vietnam).

One of the biggest factors in pricing is order quantity. We understand that you want to maximize profitability while maintaining the appropriate amount of inventory. Our team can provide you with estimates across a range of production quantities so that you can choose the option that works best for you.

Please note that any product development costs and shipping/freight forwarding expenses will not be included in your custom manufacturing quote; they will be quoted separately if they are part of the services we are providing for you.

Do you have a minimum order quantity?

The minimum order quantity for custom manufactured products is typically 5,000 units. Minimums can vary depending on the nature of the product. Minimum order quantity may be as low as 2,500 units for sourcing existing components.

Where do you manufacture products?

We work with manufacturing partners in mainland China and Vietnam to produce your products. We maintain close relationships with factory owners and senior management and regularly conduct site visits to ensure all production adheres to our high standards.

How do you ensure quality control during production?

Quality control inspections are a standard part of our project management process. The factory personnel we work with adhere to product quality levels and quality control inspection procedures that are defined by the American National Standards Institute (ANSI). Our quality control criteria are specifically defined in all of our manufacturing proposals.

We can also conduct tests to ensure that your materials will pass any required product safety tests and that the product maintains its integrity during shipping.

How can I be sure that my product isn’t copied and sold illegally?

Protecting your intellectual property is extremely important to us. We’ve worked with our overseas manufacturing partners for over 30 years, and we only collaborate with people we can trust with our clients’ projects. All of our factory partners sign non-disclosure agreements and are required to follow local regulations pertaining to copyright and patent infringement.

We recommend consulting with an intellectual property attorney if you are interested in securing additional protections for your product. We are happy to make a recommendation from our network, so please feel free to ask!

What are GPI’s payment terms and methods?

You will pay a 50% deposit upon order placement, with the balance due before your products are sent out for overseas shipping. Any preproduction setup costs for molds, color separations for printing, etc. will also be billed in advance.

Payment can be made via ACH, wire transfer, or corporate check.
