5 Ways to Make Plastic Parts, All in One Place
There are five main ways to turn plastic into finished parts. Each way works best for a certain shape, size, and number of parts. We pick the right one for your project.
Plastic Injection Molding
We push melted plastic into a metal mold to make solid parts. Great for housings, gears, and clips. We can also bond metal inside plastic or mix two plastics in one part. Accurate to 0.05 mm. Steel molds last for over a million parts.

Plastic Extrusion
We push melted plastic through a shaped opening to make long parts like tubes, seals, and channels. The plastic comes out in one long piece, and we cut it to the length you need. Works with PVC, PP, PE, PC, and PA.

Blow Molding
We blow air into hot plastic inside a mold to make hollow parts like bottles, tanks, and ducts. The plastic stretches to fit the mold shape with even walls. After molding, we trim, drill, and test for leaks. Learn more about how blow molding works.

Thermoformed Blister
We heat a flat plastic sheet until it gets soft, then press it over a mold to take a shape. Perfect for trays, clamshells, and product packaging. We can make them anti-static so they protect electronics, or strong enough to reuse many times.
See thermoforming →
Plastic 3D Printing
We build parts one thin layer at a time using a 3D printer. No mold needed, so it's perfect for testing ideas fast or making just a few parts. We print with ABS, TPU, PEEK, PC, PLA, and Nylon. We can even mix soft and hard plastics in one part.

Why Big Companies Pick Meco for Plastic Parts
One supplier handles everything. We control every step and meet auto-industry quality standards.
All 5 Methods Under One Roof
You won't need to deal with different shops for injection, blow, extrusion, and thermoforming. We do all five in one place, with one order and one engineer who looks after your project.
We Build Our Own Molds
We design and cut molds in our own shop using CNC machining and heat treatment. Fast aluminum molds take 2 to 3 weeks. Tough steel molds take 4 to 8 weeks.
We Check Your Design First
Our engineers look at your drawings before we cut any steel. We check angles, wall thickness, gate spots, and plastic choice. See how to pick a molding partner.
Top Quality Stamp (IATF 16949)
We meet the highest quality standard used by car makers. We use it for every plastic part, with full tracking, testing, and paperwork as standard.
Industries We Make Plastic Parts For
From car interior parts to medical device covers. We pick the right plastic, method, and accuracy for each job.
Automotive Parts
We make car interior parts, dashboard trim, plugs, and engine bay parts in tough plastics like PA6 and PBT. We can also lock metal threads inside plastic housings, or add soft rubbery grips on top of hard plastic. Learn more about our automotive parts work.
Medical Equipment
We make covers for medical machines, surgical tool grips, IV parts, and trays that survive hospital cleaning. We use medical-grade PC, PEEK, and TPU. Find out more on our medical equipment page.
Consumer Electronics
We make cases for gadgets, button covers, and battery doors. The plastic comes out shiny, matte, or with a pattern straight from the mold. We can also add chrome plating, PVD coating, or paint. Read more about our electronics work and PCB assembly services.
Home Appliances
We make fridge bins, washer knobs, water tanks, and control panels in PP, ABS, and PC-ABS. For big hollow parts like soap tanks and air ducts, we use blow molding. See our full home appliance work.
Aerospace Parts
For airplanes, we make cabin trim parts, air duct clips, instrument covers, and trays that won't make static electricity. We use heat-resistant plastics like PEEK and PEI. See our aerospace work.
Industrial Manufacturing
We make plastic gears, bushings, valve handles, and machine covers in tough plastics like POM (Delrin) and Nylon. Adding glass fibers makes them stronger for parts that carry loads. Read our guide to industrial manufacturing.
Telecom
We make plug housings, cable holders, fiber trays, and outdoor box parts. We use flame-safe plastics like PC, PBT, and PC-ABS. For outdoor use, we add sun-proof plastic so it doesn't crack. See our telecom work.
Lighting
We make light lenses, diffusers, reflector covers, and trim in clear PC and PMMA. The mold gives us clear, frosty, or textured looks straight away with no extra polishing needed.
Heavy Equipment
For construction machines, we make grips, knobs, fluid tanks, and protective covers in Nylon and TPU that don't crack or wear out. Blow molding handles big hollow parts like fuel tanks.
Commercial Furniture
For office furniture, we make chair shells, armrests, cable grommets, drawer slides, and adjustment knobs in PP and ABS. We can add soft rubbery overmolding for comfy grips.

Common Questions About Injection Molding
How much does a mold cost?
A fast aluminum test mold costs $2,000 to $8,000. A softer steel mold for medium runs costs $8,000 to $25,000. A hard steel mold for big production runs costs $20,000 to $80,000 or more. The price depends on how big the part is and how tricky the shape is. Hard steel molds can make over a million parts.
How much does each plastic part cost?
Small parts in common plastics (PP, ABS) cost 10 cents to $1 each. Bigger or fancier parts (PC, Nylon) cost 50 cents to $5 each. Special plastics like PEEK or glass-filled mixes cost $3 to $30 or more. The more parts you order, the cheaper each one gets.
How long until I get my parts?
A fast aluminum mold takes 2 to 3 weeks to build. A steel production mold takes 4 to 8 weeks. Once you approve the first test samples, we can ship parts in days or weeks. We send you a price quote in under 24 hours after you send your drawings.
How accurate can the parts be?
Our standard accuracy is 0.05 mm, which is thinner than a human hair. For special features, we can hold even tighter sizes by carefully designing the mold and controlling cooling. Read our guide to injection molding for more details.
Should I use injection molding or thermoforming?
Injection molding is best for small parts with tricky shapes when you need lots of them. Thermoforming is best for big flat parts and trays when you only need a few. Get the full picture in our injection molding vs thermoforming guide.
Can you do two-shot or overmolding?
Yes. We can put metal pieces inside plastic parts, or stick two plastics together (like soft rubbery TPU on hard PC for a comfy grip). Learn more in our two-shot molding guide.
What's the smallest order you accept?
There's no strict minimum. With our fast aluminum molds, 100 to 500 parts work great for testing ideas or small pilots. Injection molding usually makes sense when you need at least 1,000 to 5,000 parts a year. For just a few parts, 3D printing may be a better fit.
Do you put parts together too?
Yes. After molding, parts can go straight to chrome plating, PVD coating, painting, pad printing, or ultrasonic welding. We can also do full mechanical assembly. One supplier handles the whole job.
What quality certifications do you have?
We have IATF 16949:2016, the top quality stamp used by car makers. It includes everything in ISO 9001:2015. We follow strict steps like APQP, PPAP, SPC, and PFMEA. We also provide REACH and RoHS papers. Our factories are in Thailand and China, and we run everything from Canada. Learn more about Meco.
