The Step-by-Step Process of Creating a Custom Thermoformed Tray at Megapac

Home > The Step-by-Step Process of Creating a Custom Thermoformed Tray at Megapac

When it comes to custom plastic packaging, businesses need more than just a supplier—they need a partner who understands product protection, presentation, and precision. At Megapac Manufacturing Pte Ltd, we guide clients through the full thermoforming process, from concept to final production, all under one roof in Singapore.

In this post, we walk you through our step-by-step thermoforming process, so you can understand how your packaging trays are created—and why partnering with Megapac means faster lead times, greater control, and superior results.


🏁 Step 1: Understanding Your Product & Requirements

Every successful tray starts with understanding:

  • The size, shape, and fragility of your product
  • Packing and transportation methods
  • Industry-specific needs (e.g., food safety, ESD protection, stackability)
  • Branding or visual display goals

We work closely with you to define the functional and visual goals of your tray packaging.

Industries we serve:
Electronics, medical, FMCG, logistics, automotive, and more.


🧩 Step 2: Packaging Design & 3D Modeling

Once we understand your needs, our design team creates a custom tray layout. We use:

  • 2D CAD drawings
  • 3D modeling software (e.g., SolidWorks)
  • Precise part measurements or sample scanning (if needed)

This step ensures form, fit, and function before we proceed to production.

🎯 Key features we can design:

  • Product-shaped cavities
  • Stackable ridges
  • Finger holes for easy removal
  • Branding embossing or labels

🛠️ Step 3: In-House Aluminum Mold Fabrication

Unlike many suppliers who outsource tooling, we manufacture our forming molds in-house. This means:

  • Faster turnaround (typically 3–5 working days)
  • Design updates can be made quickly
  • You save on mold outsourcing costs

Our CNC-machined aluminum molds ensure dimensional accuracy and repeatable quality for every tray.


🔥 Step 4: Thermoforming the Tray

We load high-quality PET, PP, or ESD-safe plastic sheets into our thermoforming machines, then:

  1. Heat the plastic sheet to a soft, pliable state
  2. Form it using vacuum pressure over the aluminum mold
  3. Cool the newly formed tray to retain its shape
  4. Trim the excess edges with precision

At Megapac, our machines are calibrated for consistency, precision, and efficiency.


🧪 Step 5: Quality Control & Sampling

Before proceeding with mass production, we conduct:

  • Dimensional checks against the 3D model
  • Fit tests with your actual product
  • Material quality verification

We provide samples for client approval to ensure that the tray matches expectations for performance and appearance.


🧯 Step 6: Mass Production & Finishing

Once approved, your order goes into full-scale production using our high-output thermoforming lines. We also offer:

  • Hole punching
  • Nesting for stackability
  • Customized carton packing
  • Labelling (on request)

With strict quality checks at every stage, we ensure you receive consistent, high-performance trays—every time.


📦 Step 7: Delivery & Customer Support

We pack your trays safely and deliver across Singapore or arrange export shipping if required. Our team stays responsive post-delivery for:

  • Feedback
  • Repeat orders
  • Adjustments for new product variations

📍 Singapore-based manufacturing means shorter lead times and greater control.
