How a Door Frame Factory Tripled Output with a Gang Rip Saw Upgrade

When you’re managing high-volume production in a door frame factory, time is money. Every inefficient step in your cutting process adds up — wasted labor, off-sized planks, costly material losses, and bottlenecks that choke throughput.

That was exactly the challenge faced by a door frame manufacturer in northern Vietnam. Their daily output was capped by outdated single-blade saws, frequent material jams, and inconsistent cutting precision. The factory’s manager knew it was time for a serious upgrade — and turned to a gang rip saw system for the solution.

The Bottlenecks: Manual Sawing, Low Yield, High Labor Cost

Before the upgrade, workers used a combination of band saws and handheld circular saws to rip large wood planks into the thinner strips required for door frames. This process was:

• Slow — one plank at a time, with multiple passes
• Inaccurate — variable cutting widths and warping
• Labor-intensive — requiring 3–4 workers on the line
• Wasteful — significant material lost in uneven trimming

The result? An average of 400–500 pieces per day, often requiring rework or correction before assembly.

The Solution: HD1300 Gang Rip Saw by Hengda

After evaluating options, the factory invested in the Hengda HD1300-XD3L, a multi-blade gang rip saw optimized for panel and door frame production.

Key reasons for choosing this model:

• Adjustable blade spacing – to suit different frame designs
• High-speed feeding system – up to 17 m/min, adjustable via inverter
• Lower spindle – offering clean, splinter-free cuts
• Precision control – cutting width tolerance within ±0.2 mm
• Heavy-duty rollers with spring-loaded hold-downs – ensuring stability during feeding

Immediate Impact: Output ×3, Rework Down 80%

Just two weeks after installation, the difference was dramatic:

The gang rip saw handled the full-size plank input and ripped them into finished-width door frame strips in a single pass. Downtime dropped, reject rate plummeted, and the factory was able to take on two new clients due to increased capacity.

What the Customer Said About Gang Rip Saw

“We used to spend an entire morning just cutting the wood for 50 doors. Now, we do the same volume in under two hours — and the precision has never been better. No more headaches with misaligned joints.”

“There were days we had five workers sweating it out just feeding planks into handheld saws. Dust everywhere, offcuts piling up, and we still couldn’t meet our weekly targets. Worse, the variations in cutting width led to joint fitting problems down the line — especially in our premium doorframes.”

“The team was honestly skeptical at first — one machine doing what four of us did? But within the first week, it was clear. The feed rollers gripped the planks firmly, the cuts were clean and consistent, and our carpenters noticed they didn’t have to trim or sand the edges before assembling.”

“We cut labor down to two operators on the line. And we now finish our weekly cutting workload in three days. That gives us room for urgent orders, and we even accepted a new client who was previously too large for us to handle.”

Lessons for Other Woodworking Factories

If you’re still relying on single-blade saws or semi-manual methods, this case is proof that upgrading to a gang rip saw isn’t just a time-saver — it’s a scaling solution.

Gang rip saws like the HD1300 series:

• Allow you to standardize your output
• Reduce dependency on skilled operators
• Maximize material use with tight tolerances
• Integrate into automated production lines

Conclusion

Door frame production is all about precision, efficiency, and throughput — and a gang rip saw unlocks all three. Whether you’re supplying builders, furniture makers, or export markets, this kind of upgrade can redefine your cost structure and competitive edge.
