CASE STUDY

Tanney Candle Sleever

Equipment Type Wraparound Sleever Cartoner
Service Featured Set to Size
Date Added 7/8/2013

SIGMA Equipment helps a manufacturer of jarred candles automate a candle sleeve handwork operation, saving substantial labor and material costs.

SITUATION

SIGMA’s customer designs, manufactures and markets candles and home fragrance products. They contacted SIGMA Equipment regarding cost-effective ways to automate their processes to meet growing customer demand. They presented two sizes of glass jar candles, both with different retail sleeve designs. Previously, the sleeving process was hand-operated with 4-6 employees opening pre-glued fiberboard sleeves and inserting the filled glass jars. Transitioning to an automated sleeving process would allow them to increase their production rate and lower assembly costs.

REQUIREMENTS

SOLUTION

SIGMA Equipment’s engineering staff evaluated the products and identified a Tanney Automatic Inline Sleever as a good foundation for the project specifications. The machine was then adapted for the customer’s specific candle sizes and sleeve designs.

The reconditioning of the equipment included the repair/replacement of all broken or worn parts. The machine was cleaned, a new powder coating applied to the frame and cover panels, and all plexiglass guarding was replaced.

The retooling process to fit the machine for the product specifications included:

With all work complete, a Factory Acceptance Test was conducted prior to shipping. The test evaluated performance during both a 3-minute sprint test at full speed and a 6-minute endurance test at 75% of full speed. Both tests proved successful, resulting in 99% or more acceptable product as required by the customer. The machine was then skidded and shipped to the customer.

Upon arrival at their production facility, a second acceptance test was conducted and passed with accepted run and error rates. The machine was immediately placed into production.

RESULTS

The rebuilt equipment allowed the company to quickly increase their production to meet customer demand and reduce assembly costs, with an estimated savings of $130,000 over purchasing similar equipment new. By transitioning their candle sleeving operation from hand-operated to automated, the customer was able to reduce required labor from 4 operators to 1/2 operator, shared between material replenishment on the sleeving machine and a downline case erector. This gives them the potential to save more than $280,000* per year in labor costs on the sleeving process alone. Additional savings will be realized through the reduction of packaging material waste.

The project was completed to customer specifications, on budget and within the accepted timeframe.

* Cost savings calculated using standard burden rate of $40 per hour for 3.5 full-time hand operators.
