Custom plastic engineering for products that don't exist yet. PTM brings a full engineering bench — design, materials, tooling, validation — and AI-enabled smart manufacturing to take your brief from CAD to production. Your IP. Your specs. Our R+D bench.
PTM's engineering bench is a single integrated team — design engineers, materials scientists, tooling specialists, and quality engineers — that takes your brief from concept to production-ready specification. No handoffs between vendors. No CAD-to-quote-to-tooling-to-production fragmentation.
From concept sketches to PPAP-ready specifications. PTM design engineers bring DFM input that improves your design before tooling — reducing cycle time, material cost, and time-to-production. Co-engineering, not just CAD execution.
PTM materials engineers select, formulate, and validate plastic compounds against your performance requirements. Standard polymers for distribution-grade programs; custom resin formulations for specialized applications including FDA-grade, cold chain, UV-resistant, and impact-rated grades.
Tooling engineering on bench — prototype molds (3D-printed for short-run validation) to hardened production tooling. Single source CAD to ship. Your molds or ours.
Quality engineers run validation against your spec — first-article inspection, capability studies, material certification, PPAP submission. Every program ends with documentation.
PTM's floor runs AI-vision QA on every unit, captures process telemetry, and maintains lot-to-lot traceability from raw resin to shipped part. How we hit ±0.05 mm at scale.
Computer vision inspects every unit for dimensional defects, surface anomalies, and material consistency. 99.94% inspection rate, 0.06% escape rate. Full inspection, no batch sampling.
Every line streams telemetry — temperature, pressure, cycle, dimensional output. SPC alerts engineers before drift becomes defect. Predictive maintenance before failure.
Every shipped unit carries lot-to-lot traceability — raw resin batch, production date, machine ID, operator, QA record. Recall-ready by design.
Material consistency verified across production runs and across years. Mold variance under 0.3 mm across production years. Statistical capability indices documented for every program. Your spec at month 1 is your spec at month 36.
PTM's engineering bench operates across eleven capability domains — the verticals where our materials, tooling, and quality systems align with industry-specific requirements. Active programs in each domain available under NDA.
Stackable furniture, folding tables, returnable transport for venue operations. High-cycle commercial use, scratch-resistant, rapid setup/teardown.
Branded refrigeration, can/bottle organizers, POS displays. High-traffic retail, custom OEM colorways, integrated branding, impact-resistant.
Vented containers, insulated transport, FDA-grade returnables for produce, protein, prepared foods. −20 °C to +60 °C with thermal-cycle integrity.
Stackable totes, returnable transport, AS/RS-compatible storage. High-velocity DCs, automation-ready precision, closed-loop returnable programs.
Hard-sided coolers, rugged transport, UV-resistant outdoor gear. Impact resistance, color-stability, extreme-temp integrity.
PPAP-ready components, dunnage trays, returnable systems for Tier 1 automotive. ±0.05 mm, AI-vision QA, lot traceability — built to OEM/Tier 1 spec.
Anti-static trays, custom protective housings, ESD-safe transport. For circuit-board logistics, semiconductor handling, electronics aftermarket.
Custom POS displays, branded packaging, in-store fixtures. Retail-floor durable, custom OEM branding, quick-change merchandising.
Field harvest crates, stackable produce bins, FDA-grade containers for agriculture. Outdoor exposure, wash cycles, seasonal throughput.
Heavy-duty tool boxes, parts bins, line-side organizers. Impact-resistant, oil/chemical-exposure rated, assembly-line integrated.
UV-rated, salt-resistant, marine-grade plastic components. Built for saltwater, marine cycles, exterior durability.
Every custom program runs through the same five-stage process — clear deliverables, clear timelines, clear handoffs. No scope creep.
Numbers that matter when you're choosing an engineering partner. Updated quarterly.
Anonymized profiles from the active portfolio. Real operational problems, PTM approach, outcomes — within validated capabilities and NDA.
Tier 1 stamping operation in the Midwest needed to standardize returnable dunnage across three plants. PTM Custom Plastics designed a single SKU replacing four legacy variants, PPAP submission delivered on first attempt.
Top-50 CPG beverage brand operating DSD across 38 U.S. markets needed color-coded totes for route segregation. PTM delivered the first wave from stock with brand Pantone matching.
Mid-market 3PL with six Midwest DCs needed to standardize tote inventory after acquiring three operators. PTM Stackable Totes replaced 11 legacy SKUs, converting pools into shared infrastructure.
Top-20 frozen food manufacturer needed pallets maintaining dimensional stability between freezer storage and ambient dock. PTM Stamina line replaced wood pallet inventory.
Top-50 e-commerce operator deploying AutoStore needed tens of thousands of grid-compatible totes in a fixed window. PTM standard portfolio covered the first wave; custom run scaled behind schedule.
Industrial OEM with novel returnable packaging needed a plastic prototype manufacturer moving from CAD to PPAP-ready production on one bench. PTM handled CAD validation, prototype tooling, stress test, and pilot production.
For teams evaluating a partner against a prototype-to-production timeline — what PTM's prototyping process looks like and how it integrates with PPAP-ready production.
PTM operates as a plastic prototype manufacturer moving CAD to PPAP-ready production on one bench. Process: CAD validation, DFM, 3D-printed form/fit, soft-tooled prototypes, stress-test, pilot production.
Soft tooling (aluminum, single-cavity) supports prototype and low-volume programs. Hard tooling (steel, multi-cavity) supports production-scale custom injection molding. Right path scoped against target volume during the engineering consult.
AI-vision QA applies to prototypes and production. Dimensional data on prototype runs surfaces issues before reaching production tooling. Iteration cycles typically run two to four weeks per round.
For PPAP-ready submission from day one, the data trail starts at prototype: capability studies, dimensional results, material certs at resin selection.
If it's plastic

Schedule WorkshopPTM operates standard NDA on every custom program. Your designs, your specs, and your IP remain yours. PTM does not retain or reuse customer-specific designs, tooling, or material formulations. Work-for-hire is the default contract model; licensing arrangements are available for hybrid programs and discussed per project.
For programs requiring extended IP protection beyond standard NDA — including escrow arrangements, geographic exclusivity, or production-rights restrictions — these are discussed at the brief stage and structured into the contract before any CAD review.
