Looking to sell your used plastic machines? Whether you’re upgrading your shop floor or simply freeing up space, finding the right marketplace can make all the difference in turning idle equipment into cash. In this guide, we’ll walk you through the top platforms and strategies to list and sell your pre-owned injection molding machines quickly and profitably.

1. Industry-Specific Equipment Marketplaces

Specialized marketplaces attract serious buyers who know exactly what they want.

• Plastics Machinery Exchange
  A go-to site for North American buyers and sellers of injection molders. Detailed equipment specs and photos help your listing stand out.

• MachineTools.com
  Features a dedicated plastics section; it’s well-trafficked by manufacturing plants and equipment dealers.

• EquipNet
  A global asset-management firm that lists pre-owned industrial machinery, including injection molders, with robust auction and direct-sale options.

Tip: Include clear photos of controls, molds, and any wear areas, plus machine serial/model numbers, to build buyer confidence.

2. General Industrial Marketplaces

For broader exposure, consider diversified industrial equipment sites:

• eBay Industrial & Scientific
  Ideal for smaller machines or lower-priced units. eBay’s auction format can sometimes drive prices above market value when multiple buyers compete.

• Bid on Equipment
  Hosts both auctions and classified ads, reaching buyers in dozens of countries.

• Alibaba
  If you’re open to exporting your machine, Alibaba’s massive user base can unlock international leads.

Tip: Be crystal-clear on shipping logistics—machine weight, dimensions, and whether you’ll handle crating or loading.

3. Equipment Dealers and Brokers

If you prefer a hands-off approach, equipment dealers and brokers can manage the sale from listing to shipping:

• Local Machinery Dealers
  Dealers often maintain waiting lists of buyers looking for specific models and can sell on consignment.

• Industrial Auction Houses
  Great for selling multiple machines at once; they handle marketing, inspection, and bidding events.

• Independent Brokers
  Charge a commission (typically 5–15%) but can tap into niche buyer networks for higher sale prices.

Tip: Vet your dealer or broker by asking for recent sales history, references, and their preferred commission structure.

4. Industry Associations & Trade Publications

Tap into print and digital resources that cater specifically to plastics professionals:

• Plastics News Classifieds
  Both online and in-print options; readers are industry insiders actively seeking equipment.

• Society of Plastics Engineers (SPE) Marketplace
  Post classifieds to reach SPE members globally.

• Local Trade Journals
  Many regions have manufacturing newsletters or magazines with classifieds sections.

Tip: Ads in trade publications often include a longer lead time (2–4 weeks to publish), so plan ahead if you’re on a tight timeline.

5. Online Forums & Social Media Groups

Engaging directly with the plastics community can help you connect with end users and small shops:

• LinkedIn Groups
  Groups like “Plastic Injection Molding Professionals” or “Plastics Manufacturing” allow you to post equipment-for-sale listings and engage with buyers.

• Facebook Marketplace & Groups
  Search local and regional “industrial equipment” groups—these can yield quick leads for nearby buyers.

• Reddit (r/PlasticMolding, r/Manufacturing)
  While not a traditional sales channel, posting “WTT” (want to trade/sell) can attract hobbyists or smaller converters.

Tip: Always follow each group’s rules on commercial postings, and include a link back to your more detailed listing on a marketplace or your company site.

6. Your Own Website & Email Newsletter

Don’t underestimate the power of your own digital real estate:

1. Dedicated Equipment Page
   Create a “Used Equipment for Sale” page on your company site, optimized around the keyword sell your used plastic machines.

2. Email Blasts
   Notify past customers and newsletter subscribers when you have a machine for sale—these warm leads often convert more quickly.

Tip: Include a clear call-to-action (“Contact us for a quote,” “Schedule a site visit”) and an inquiry form to capture buyer details.

7. Tips for Maximizing Sale Price

1. Perform Basic Maintenance
   Clean the machine, top up fluids, and replace worn hoses or filters—small investments can justify higher asking prices.

2. Gather Documentation
   Provide maintenance logs, parts manuals, and electrical schematics to demonstrate reliability.

3. Offer Inspection Opportunities
   Invite serious buyers to your facility or provide a live video walkthrough to showcase machine condition.

4. Flexible Payment & Financing
   Partner with equipment financiers to offer lease-to-own or installment plans that broaden your buyer pool.
