Foodservice Equipment OEM Onshores to Weather the Perfect Storm, Taps Rahco to Fill Production Gaps and Quality Concerns

Global supply chain disruption, extended lead times from an offshore supplier, and formulation concerns rising from a volatile polymer market began to forecast a Perfect Storm that this foodservice equipment manufacturer couldn’t weather .

The distress call went out when this industry leading OEM experienced production line down periods due to an offshore supplier’s inability to provide key assembly components. The OEM was also concerned that the material used for their component had been manipulated due to raw material allocations and force majeure challenges.

Rahco stepped up and conducted material validation and compliance performance specification testing, rapid proto-typing, and expedited production tooling.

Rahco’s chemists and on-staff material science experts developed and tested a formulation based on most available raw materials that satisfied the customer’s high performance and ASTM D2000 specifications. Rahco’s design and engineering team worked with the client’s tooling sources to compress deliverable dates for a top-quality production mold; facilitating a production-intent proto-type mold that was completed in 4-weeks, and a production mold to meet a high-volume EAU that was delivered within 9 weeks.

Rahco successfully eliminated the supply chain gap, reduced lead times by 80%, and introduced a robust custom formulation that exceeded expectations and field requirements. Confidence in the critical formulation as restored and the brand’s integrity was protected.

Rahco Assumes In-House Rubber Molding when this Global Energy Leader faces Labor, Equipment, and Production Deficits

A global leader in the Oil & Gas industry realized that their ancillary in-house rubber molding operation required new equipment . . The division was also occupying valuable floor space and pulled much-needed human resources away from its strategic product manufacturing and core competencies.

Rahco immediately assessed the energy company’s goals and not only catered to its rubber molding needs, but redesigned the critical tooling to more-than-double the production output per cycle.

By outsourcing critical component manufacturing to Rahco, the customer was able to optimize its workforce and repurpose significant labor, reappropriate approx. 4,000 sqft. of existing floor space that had been used for molding operation, as well as avoid approx.$1M in CapX for a non-core operation because Rahco was able to make the investment in necessary machinery and assumed expenditures for two new dedicated presses. Rahco’s production also exceeds demand requirements and delivers finished good volume targets that prevent a future backlog.

Polishing Production — Rahco Brings Global Oral Health Medical Device from Concept to Commercialization. Molded. Over-Molded. Assembled. Bagged. And Shipped

For years, Rahco Rubber has partnered with a global oral health leader who has set the standard for dental manufacturing, technology, and treatment for over a century. Its class-leading medical devices and dental tools span a range of categories, all of which require the most advanced engineering and design — and when it comes to precision rubber prophy cups used by dentists to polish teeth, nothing is left to chance.

The components features complex geometry, molded with a pure White FDA compound that must be formulated to exacting specifications not only to meet various medical compliance, but protect the customer’s brand as a trusted name in the dental space and oral health care innovator.

After millions of parts produced with zero defects, Rahco continued to keep the customer smiling bright and helped support its decision to outsource the entire molding operation. This required great trust and collaboration, as Rahco would assume the entire development of multiple versions of the part.

Rahco setup an advanced production cell and began producing additional parts with processes to develop the prophy cup in additional, complex formats capable of being positioned easily onto the handle of the dental polishing tool. These included the initial snap-on part, as well as other versions with a more elaborate process with the compound over molded onto a plastic stem and another that is over molded onto a brass stem for various applications in the field.

The decision the OEM made to close its facility and transition everything to Rahco proved to be a win-win and helped avoid timely and expensive steps. Rahco researched and acquired a new automatic bagging machine to streamline final production, labeling, and shipping of a finished product. The completed parts are entirely outsourced with greater quality and significant cost savings and operational efficiencies for the medical device manufacturer.

Life Saving Over Molding — Rahco Addresses Delamination Issues with Rapid Inflation Flanges used on Lifeboats to Ensure Zero Defects

For nearly three decades, this high precision equipment manufacturer has been serving a range of industries with complex, assembled components that are second to none — including the customizing valves and flanges that fit the unique needs of life rafts, inflatable jackets, helicopter floats, marine evacuation systems and the alike.

The company produces a very high-quality brass component used on lifeboats as part of a critical rapid gas inflation control equipment. It had been sourcing a finished product that featured an over molded rubber brass substrate. Before the OEM worked with Rahco, it was concerned with a rubber to metal bond failure and needed greater certainty that the rubber wouldn’t delaminate. Among other quality control and continuous supply challenges, it turned to our team at Rahco for help.

As with any rubber-to-metal bonding, which can be achieved via a mechanical or chemical process, the substate, final part design and materials determine the best method. So, Rahco analyzed the all of the contributing factors and determined a robust system for success. Additionally, a new tooling design was recommended to allow for greater throughput resulting in production with zero defects.

Using the high-precision apparatus provided by the customer and over molding a Neoprene compound, Rahco delivers finished high-quality goods much more consistently that boosts the component’s reliability and achieves long service life in saltwater environments to meet the high standards for maritime safety. Rahco also ensures greater on-time delivery, overall production efficiency improvements, and most importantly, no delamination. The customer has since asked Rahco to mold four other finished parts for other advanced equipment serving life-critical sectors.

Irrigation & Agricultural Industry OEM

Challenge:

The need for added capacity because of increased customer orders continue to grow. The current part of Rahco molds is 90% of their product line with EPDM and FKM produced using the same tool made 18 years ago. EPDM is approximately 6 times the volume of the FKM part.

Goal:

Bring on a second mold for risk management purposes. Support the growing backlog with customer orders.

Rahco’s Approach:

  1. Capital investment – 1 new vertical injection press and 1 new horizontal press.
  2. Tool up a multi-cavity injection mold dedicated to producing the EPDM part only utilizing the latest flashless molding technology.
  3. Output per cycle 4-5 times greater than the conventional tool made 18 years ago.

Net Wins:

Customers will now be able to better manage their backlog. Rahco incorporated a flashless tool design which eliminated the need to cryogenically de-flash the parts; delivering time and cost savings. The customer now has a dedicated mold for FKM and a new mold for EPDM parts. Rahco not only solved their need for added capacity but additionally saved their customer $30,000.00/year with a reduced piece price.

Narrative:

A large company heavy in the agriculture sector came to Rahco asking how we can increase capacity due to their ever-growing business. After much internal discussion as to the best approach, we were able to successfully offer a proposal that would work for both parties. Rahco once again was able to satisfy another customer and offer savings. It’s what we do. Let us help you too!

Rahco Creates A Fairy Tale Of Savings

The tale of the Two-Piece Assembly Structural Plumbing Seal & Fastener. What began as an “inherited” hot pot transfer mold from a customer struggling with quality and hurting from costs soon became a Value Added Value Engineering (VAVE) opportunity when Rahco proposed a low waste flashless mold and transfer cold pot production process! Later on, when suffering with concentricity issues of the mating plastic component, Rahco stepped in again and retooled for this plastic component. Rahco then created an automated 2-component assembly cell that saves this customer over a $100,000 on an annual basis! And they lived happily ever after.

Rahco Develops Flashless, Low Waste Rubber Mold Without Secondary Operations

A major OEM came to Rahco with a recurring problem that was jeopardizing their standing with a very important customer. The problem was inconsistent material along with unpredictable delivery and unacceptable part attribute qualities from their previous rubber molder. In order to maintain a required price point, material for a very low volume swell in gasoline was needed that would not use a super-premium polymer.

Rahco developed a compound that not only solved the swell issues in gasoline but additionally was very robust from a molding standpoint. The end result was the development of a flashless and low waste rubber mold that produced parts with zero defects and a bare minimum of residual waste. Parts are produced and packed right at the molding press without secondary flash removal or inspection operations.

This successful project has allowed us to grow with this customer and enjoy a mutually beneficial relationship.
