Large Part Plastic Injection Molding Company

What Is Large Part Injection Molding?

Large part injection molding is a specialized process used to produce oversized plastic components using advanced injection molding machinery with higher tonnage and larger mold capacity.

Unlike standard molding, injection molding of large plastic parts requires:

• Bigger mold bases

• Higher clamping force (often 1000 to 3000 tons)

• Precise temperature and pressure control

• Expertise in material flow, cooling, and warpage management

This process allows you to produce large injection molded parts that maintain structural strength, dimensional stability, and perfect surface finish — no matter the size.

At LXG Injection Molding, we handle plastic injection molding for large parts using state-of-the-art presses and optimized tooling design to ensure every product meets your functional and aesthetic requirements.

Common Applications of Large Plastic Injection Molding

When people think of “large plastic parts,” they often picture automotive bumpers — but the possibilities go far beyond that.

Our large part injection molding service supports industries such as:

• Automotive: dashboards, bumpers, grilles, battery enclosures, door panels

• Industrial Equipment: machine housings, guards, trays, covers

• Agriculture: tanks, containers, irrigation system components

• Medical: large device housings, imaging system frames

• Aerospace: lightweight structural parts and interior panels

• Consumer Products: furniture, storage bins, sports equipment

• Construction: lighting fixtures, panels, enclosures, and covers

If it’s big, durable, and made of plastic — chances are, LXG Injection Molding can mold it.

Our Process: From Concept to Large Injection Molded Parts

Every project at LXG Injection Molding follows a structured, collaborative process designed to minimize risk and ensure precision at every stage.

Step 1: Consultation & Design Review

We start with your design files and discuss functional requirements, material selection, and aesthetic goals.
Our engineers perform DFM (Design for Manufacturability) analysis to catch potential issues early.

Step 2: Mold Design & Engineering

Using advanced CAD/CAM systems, we design your mold to optimize flow, cooling, and cycle time — essential for large part injection molding success.

Step 3: Mold Manufacturing

Our tooling department fabricates the mold using high-grade steel and precision CNC machining.
We also perform mold flow simulations to ensure even material distribution across large surfaces.

Step 4: Sampling & Testing

Before production begins, we run sample parts to test dimensions, strength, and surface quality.
Every prototype undergoes FAI (First Article Inspection) and CMM (Coordinate Measuring Machine) verification.

Step 5: Full Production

Once validated, your project moves into full production.
Our presses can handle plastic injection molding of large parts up to several meters in length, maintaining tight tolerances throughout.

Step 6: Finishing & Assembly

We provide secondary processes including trimming, painting, pad printing, ultrasonic welding, and sub-assembly if required.

Step 7: Packaging & Global Delivery

All parts are carefully packed, labeled, and shipped directly to your facility — whether you’re in the USA, Europe, or Asia.

Materials Used in Large Part Plastic Injection Molding

Material choice matters — especially for large parts that need to balance weight, durability, and performance.

At LXG Injection Molding, we work with over 100+ material grades, including:

• ABS (Acrylonitrile Butadiene Styrene): strong and impact-resistant

• Polypropylene (PP): lightweight and chemical-resistant

• Polycarbonate (PC): transparent, rigid, and heat-stable

• Nylon (PA66/PA6): excellent mechanical strength and wear resistance

• HDPE / LDPE: perfect for tanks, bins, and large containers

• Glass-Filled Resins: reinforced for strength and dimensional stability

• Recycled & Eco-Friendly Materials: sustainable options available

If you’re unsure which resin suits your large component, our team will recommend the ideal choice based on strength, cost, and environment.
