Used Case Erectors

Used Case Erectors for a Faster, Steadier Packing Line

Feeding a packing line by hand only works until your volume catches up with you. A case erector takes over the tedious part – pulling flat blanks from a magazine, squaring them into boxes, and sealing the bottoms – so cases reach your packers ready to fill. Our used case erectors handle that job across a range of speeds and case sizes. If you’re weighing a used case erector for sale, give us your case dimensions and line speed and we’ll help you narrow it down. Call CWR Resources at (630) 262-9595.

What does a case erector do?

A case erector automatically forms corrugated shipping cases from flat, knocked-down blanks. It draws a blank from its magazine, opens and squares it, folds the bottom flaps, and seals them with pressure-sensitive tape or hot-melt glue – handing off an open, square case that’s ready to pack. Most machines form standard RSC cartons (the familiar slotted shipping box) and related styles at speeds measured in cases per minute. By taking over hand assembly, a case erector steadies your throughput and frees up people for packing, whether you’re running food and beverage, consumer goods, e-commerce and distribution, or similar operations.

Types of used case erectors we stock

Case erectors mostly differ in how they seal the bottom, how fast they run, and how easily they change from one box to the next. Those are the details to weigh against your line:

• Bottom seal: tape or glue. Pressure-sensitive tape is simple, low-cost, and easy to run. Hot-melt glue gives a stronger, faster bottom seal favored for heavier cases and high-volume lines, though it adds a glue system and some care around hot adhesive.
• Speed and size. Compact machines around 15-25 cases per minute suit most operations, while high-speed models run 35 cpm and up – each with its own case-size range, so throughput and box dimensions go hand in hand.
• Changeover and case hand. Some erectors are set for one consistent box; others are built for quick size changes when you run several. Note that machines are configured right- or left-handed, so the case “hand” has to match your boxes and line direction.

Case erectors typically pair with a downstream case sealer or case packer, and we carry those too – ask if you’re piecing together a full line.

Pearson case erectors

Pearson Packaging Systems has built case-forming automation for more than seven decades, and its case erectors – models like the CE25, CE35, and the faster CE50 and CE60 – are a common sight on lines that run around the clock. They use dual opposed vacuum to open each blank and synchronized flight lugs to hold the case square all the way through sealing, which helps them handle the corrugate variation that trips up lesser machines. Offered in tape or glue configurations, a used Pearson case erector is a dependable pick when uptime is the priority.

Wexxar case erectors

Wexxar (now Wexxar Bel) case erectors are known for a “pin-and-dome” forming system and dynamic flap folding that square cases reliably while keeping the machine’s footprint compact. Operators tend to like them for genuinely tool-less size changeovers and straightforward maintenance – which makes a used Wexxar case erector, such as the WF20 or WF30, a strong fit for lines that switch box sizes often or run in tight spaces.

Other brands and changing stock

Pearson and Wexxar are far from the only names we handle. We also take in case erectors from makers like OK International and other respected brands as they become available, and inventory turns over constantly – so if you have a particular brand or model in mind, check the inventory above or contact us and we’ll tell you what’s in stock or on the way.

How to spec a used case erector

Matching a used case erector to your operation comes down to a handful of specifics:

• Case sizes. Confirm the machine’s minimum and maximum case dimensions cover the boxes you run, and check which change parts are included.
• Case hand. Erectors are set up right- or left-handed – the machine has to match your box orientation and the direction of your line.
• Seal type. Tape or hot-melt glue, chosen for your case weight, speed, and budget.
• Speed. Match cases per minute to your packing line so the erector keeps pace without overshooting what you need.
• Case style. Most machines form RSC and similar boxes; if you need Bliss cases or unusual styles, that’s a different machine, so flag it early.
• Condition and intended use. Production-ready or a parts and rebuild candidate – we’ll tell you exactly where each machine stands.

The CWR difference on used case erectors

Plenty of dealers can email you a photo and a spec sheet. We’d rather show up in person. Before a case erector joins our inventory, our team goes to where it’s running or stored, evaluates it on-site, and grades it honestly – production-ready, or a candidate for parts and rebuild. It’s a habit we’ve kept since 1997, and it’s a big part of why buyers across the U.S., Canada, and Mexico keep coming back. We also stage equipment in every region of the country to keep freight sensible. And the case for buying used still holds up: proven machinery at a fraction of the price of new, and one more solid machine kept working instead of scrapped.

Used case erector FAQ

What’s the difference between a case erector and a case sealer?

A case erector forms the box and seals the bottom, leaving the top open so you can pack product into it. A case sealer closes and seals the top flaps after the case is filled. Most automated lines run both – an erector at the start and a sealer at the end.

Should I choose tape or hot-melt glue?

Tape is simpler, less expensive, and easy to run, which suits many operations well. Hot-melt glue produces a stronger, faster bottom seal that’s preferred for heavier cases and high-volume lines, but it adds a glue system and some handling care around hot adhesive. Case weight, line speed, and budget usually make the decision.

Can one case erector run different box sizes?

Within its rated size range, yes – you change the machine over from one box to the next. Some erectors change over faster (even tool-less) than others, so if you run several case sizes, changeover speed is worth weighing. Keep case hand in mind too, since the machine has to match your box orientation.

How fast do case erectors run?

Speed is measured in cases per minute (cpm). Compact machines typically run around 15-25 cpm, while higher-speed models reach 35 cpm and beyond, depending on case size and the quality of your corrugated blanks.

Can I buy a used case erector for parts?

Yes. Along with production-ready machines, we often carry older or non-running erectors that make excellent parts and rebuild sources – vacuum cups, tape heads, glue systems, drives, and more. Ask us what’s currently available.

What condition are your used case erectors in?

It varies from machine to machine, and we’ll always be clear about it. Some are production-ready and can be seen running; others are sold as-is or as parts and rebuild candidates. Because we evaluate equipment on-site before we take it in, you get an honest read on condition before you buy.

Can you help match a case erector to my line?

Absolutely. Tell us your case sizes and hand, your seal preference, and your target speed, and we’ll help you find a machine that fits. Reach out and we’ll talk it through.

Do you sell used case erectors nationwide?

Yes. With equipment stored across every region of the United States, we serve buyers nationwide, along with Canada and Mexico.

Ready to automate your box assembly?

A used case erector is one of the quickest wins on a packing line – it steadies output, takes the labor out of hand-folding, and pays back fast. If you’re ready to add one, or to replace one that’s seen better days, browse the inventory above or get in touch, and we’ll help you find a machine that fits your cases, your speed, and your budget.
