Onshoring Injection Molding: How Om Raj Tech & Jimdi Plastics Deliver Seamless Tooling Transfer

Jimdi Plastics, founded in 1997 and located in Allenale, operates a 40,000 square foot facility with 16 presses ranging from 150 to *Not specified* tons. The company specializes in providing plastic injection molding services primarily for companies that do not produce plastic parts themselves. Their expertise lies in managing plastic needs and supporting customers through onshoring and domestic transfer tooling processes, often in partnership with Amraj Tech.

 Key Insights and Core Concepts

Niche and Value Proposition

  - Jimdi Plastics focuses on customers who outsource plastic production.

  - Provides a "hands-off, out of mind" solution, managing plastic supply chains domestically.

-Onshoring and Transfer Tooling Process:

  - Success depends on a multi-point plan developed for both onshoring and tooling transfer.

  - The process begins with a competitive, accurate quoting phase, which is critical to viability.

  - Quotes require apples-to-apples comparisons based on:

    - Part weight (preferably from physical samples; CAD data is often unavailable)

    - Material type (sometimes identified by Jimdi if unknown)

    - Tool dimensions and cavitation (to compare existing overseas tooling with proposed tools)

    - Whether a new tool build or existing tool use is planned (usually new tools for onshoring because overseas suppliers often own the tools)

-Challenges in Pricing and Value Chain:

  - Onshoring tooling and part costs may initially be higher than current offshore costs.

  - Customers must consider the total value chain including:

    - Inventory carrying costs (avoiding 90 days of inventory)

    - Shipping costs and lead times

    - Cost of quality, including scrap and defect rates in offshore pipelines

    - Cash flow improvements by reducing overseas payments and lead times

    - Reduced operational stress (less after-hours troubleshooting)

  - Jimdi emphasizes open dialogue on target prices to avoid wasted time and ensure realistic expectations.

-Tool Condition and Transfer Evaluation:

  - For domestic tool transfers:

    - Tool condition is assessed via last shots, facility visits, photos, and videos.

 - Jimdi leverages a strong local tooling network in Grand Rapids, a renowned hub for injection molding tooling.

    - Tool condition dictates whether a tool can be reused or if a new tool build is necessary.

-Bank Build Strategy:

  - Usually, a bank build (production of parts ahead of transfer) is required.

  - This allows time for ramp-up and inventory to support a smooth transition.

  - Customers can opt to keep 1–2 weeks or more parts in inventory to mitigate risk.

-New Tool Build and Program Management:

  - When building new tools, Jimdi maintains:

    - Weekly updates with photos and milestone tracking.

    - Use of China-based team members to verify tooling progress and quality on site.

  - First shots (initial tool runs) are critical milestones for visual and dimensional approval.

  - There is a working process of iterative modifications, including second shots and further trials, until specifications are met.

-PPAP (Production Part Approval Process):

  - Includes documentation like:

    - DFMEA (Design Failure Mode and Effects Analysis)

    - PFMEA (Process Failure Mode and Effects Analysis)

    - Control plans dictating step-by-step production controls

    - Visual approval with master parts identifying acceptable and defective conditions

  - The customer signs off on PPAP packages before full production begins.

-Secondary Operations and Value-Added Services:

  - Jimdi offers or coordinates secondary processes including:

    - Sonic welding

    - Paint (via trusted local partners specializing in low and high volume jobs, including laser etching)

    - Hot plate welding (technical expertise available, but not currently performed in-house)

    - CNC machining of plastic parts (in-house technical expertise available, but machining not currently done internally)

    - Kitting and hand assembly

  - Secondary operations are managed to maintain quality and supply chain simplicity.

  - Quality control for secondary operations involves developing and approving master parts with suppliers.

-Maintaining Competitiveness and Quality:

  - Quality is prioritized over price.

  - Suppliers for secondary operations must meet strict quality standards through master part approvals.

  - Jimdi leverages local expertise and transparent customer communication to meet price targets.

  - Open price discussions occur about target prices, which are shared roughly 50% of the time.

  - Transparency prevents wasted time and ensures alignment on costs and expectations.
