Ball Screw

Ball Screw

We are Injection molding ball screw repair specialists. Injection molding machines use large diameter ball screws and nuts to open and close the machine. They are not available on the shelf for replacement and can take up to 8 weeks for delivery. The downtime will cost you more than the replacement unit. We can get you back into production faster than any other company.

We can repair any injection molding ball screw, regardless of make, model, size or amount of wear. Call the OEM and check the pricing and delivery times of a replacement, make sure you're sitting down, the price and wait time will shock you. Then call us, no ball screw will take more than 10 days to repair and we're guaranteed to save you up to 70% from ordering new with a longer, stronger warranty.

What will my injection molding ball screw repair cost? Typical savings are 50 to 70% of new. Call us with the approximate diameter and length. Be very descriptive on why you are sending your ball screw repair to us. Noise in one direction, growling at all times, broken flights or all the balls have fallen out. The more information you provide, the more accurately we can estimate your injection molding ball screw repair right over the phone. We'll follow up by email and fax and can even arrange for pickup of your unit the same day.

 

Mitchell Precision has an advantage over other repair shops. We can perform all OD/ID grinding, ball screw repair, nut repair, component repair, reloading and testing in house. No subcontractors means faster delivery time with lower cost. Don't let machine downtime cost you more than the repair project.

 

How long will my injection molding ball screw repair take? Depends on the problem. Simple growling and noise means the balls, nut or root diameter are worn and that is 2 to 4 days. Broken flights, all balls have fallen out means there is severe damage to the ID of the nut. That can take 5 to 7 days. Need it in a hurry? Let your tech know this is a "Red Ticked Expedite" and we can work 3 shifts including weekends and holidays to get your machine back into production ASAP.

Injection molding ball screw repair procedure

1: Complete disassembly and cleaning of all parts for visual inspection and precision measurements. Dye penetrant to check for cracks, pits, etc. Repair as needed.

2: Weld and repair any deep pits, scars, broken flights on the OD of the screw.
3: Repair the ID of the nut and precision ID grind the ball grooves to receive a larger diameter ball

4: Precision OD grind the ball groove on the ball screw to receive a larger ball, the same size as the ID of the ball nut. The ball nut usually has more wear, so that is the first grind and we go off of that ball size.

5: Repair or replace broken or worn pickup tubes (ball return tubes) with new (these are not available from OEM, these are replacement parts made by Mitchell Precision using FARO Tech 3D scanning technology and 5th axis CNC milling to exceed OEM spec/tolerances)

6: Install oversize balls to OEM preload specs. Test with weight for smooth operation and repeatability for 24 hours, approximately 250 cycles under load and different speeds.

7: Final inspection and professional crating using foam insulation and steel bands to prep for delivery.

 

The end result is an injection molding press ball screw repair that will perform like new with an 18 month warranty covering all parts and labor. All while saving you 50 to 70% from buying new in under 10 days. No other company can provide the precision rebuilding expertise and warranty of Mitchell Precision. We are the most trusted name in plastic & rubber processing in North & South America.

 

The OEM will not sell you any spare parts for your ball screw, they want to sell you the entire unit at an outrageous price and delivery time. We have parts in stock from spare nuts to spare ball return tubes to complete units. If we don’t have the parts in stock we can reverse engineer using a FARO 3D Scanning Technology combined with 5th axis CNC milling, we can duplicate any parts you might need in one or two days.

 

Injection molding ball screw exchange program: We have dozens of injection molding ball screws for exchange. Some may be a larger or longer, but we can easily machine to length (OD can’t be changed). If the pitch is different, you’ll need to reprogram your parameters to more/less turns for a full open/close cycle. It’s an easy item to reprogram and we can walk you through the parameter reprograming via video chat, free of charge.
